This causes IndexError

There was a situation when test_creating_birthday_channel was failed but test_deleting_birthday_channel was successful. It must be fixed because if test_deleting_birthday_channel works properly, it's impossible.

Improve general Rocket.Chat tests:

• use check_with_retries function instead of waiting for a specified amount of time,
• use API call where it is needed,
• transform _delete_channels to be a proper test case, use an API call to clean up environment instead.

Split host command line argument to addr and port.

• base.py
• happy_birthder_script_tests.py
• pugme_script_tests.py
• rc_tests.py
• viva_las_vegas_script_tests.py
• vote_or_die_script_tests.py
• docker/is_bot_online.py
• docker/wizard.py

test_for_adding_weekends_to_vacation doesn't check that the bot extends the length of the vacation period with weekends if the end of the period is on Friday.

Interrupt the tests if tests and Rocket.Chat server versions mismatch.

_curses.error: setupterm: could not find terminfo database

Write a method which will finalize the tests scenario (even interrupted by user) and delete all artifacts created by the tests (users, channels and so on).

By analogy with birth dates: there are two tests for 1 date and 2 dates.

The test case should simulate the following behaviour. The admin changes the value in the Accepted Media Types field, closes the administration panel, opens it again and checks that the value in the Accepted Media Types field hasn't been changed. It seems to be a bug.

Now when the user presses Ctrl+C, the current tests stop and the next ones start, resulting in the need for pressing Ctrl+C one more time.

hubot-vote-or-die allows building emojis-based polls, so there should be a test case which compares the numbers of options and the number of emojis related to them.

Allow create_user and delete_user functions getting the user object as argument. It can be the user dictionary with all necessary attributes and can mock the structure of the user object from Rocket.Chat.

test_fwd_set_for_new_user is a useless test case because it repeats test_fwd_set_for_admin.

The problem is described here.

Expand viva_las_vegas tests:

• test command список заявок
• test command @username хочет в отпуск
• test command viva reset
• test daily reminder
• test reminders to inform customer before leaving
• test filtering of inactive users
• test resetting user status after coming back from vacation and if it is impossible to ask for the second leave request

Part of these tests cases is required for the implementation of issue #68 (for test cases where multiple users are in use).

pylint complains that there to many local variables in the function.

Add correct program terminating by ctrl-C and in case of manual browser closing.

optparse is deprecated since version Python 3.2.

Provide possibility to run only tests for specified script without running the general RocketChat tests.

I guess in general it is better to check all requirements for all scripts before running the tests. In other case I need to wait again for running all general RochetChat test to get the info that it is lack of some mandatory parameters for birthder tests (which is not mentioned in README).

Now we can see only finished tests. And we can't know what test is executing right now. It would be great if we can see it

Use API calls in happy_birthder_script_tests.py to improve tests or get an unconditional result where it is relevant.
