Apply rubocop about ib-api HOT 2 OPEN

Hi,
I was unable to run the tests after applying the changes.
Got

newdevel:~/workspace/ib-api$ bundle exec guard
18:46:25 - INFO - Guard::RSpec is running
18:46:25 - INFO - Guard is now watching at '/home/ubuntu/workspace/ib-api'
18:46:54 - INFO - Running: spec/ib/connect_spec.rb

An error occurred while loading spec_helper.

revoked the merge into to master branch.

Lets look together, what went wrong (mail me: topofocus@gmail,com)

Hi,
using the improved random id generation I run in some trouble

newdevel:~/workspace/ib-api/bin$ ./console 

>> IB-Core Interactive Console <<
---------------------------------------------

Namespace is IB ! 

---------------------------------------------
Connected to server, version: 137,
 connection time: 2020-10-15 12:47:44 +0000 local, 2020-10-15T12:47:43+00:00 remote.

TWS Warning 2107: HMDS data farm connection is inactive but should be available upon demand.ushmds
newdevel:~/workspace/ib-api/bin$ 

the console does not start

First I changed the method name to 'generate', because ib-api at some point tests if a Constant responds to call.

Same result.

When i switched bach to `random 99999' anything works fine again.
Then

newdevel:~/workspace/ib-api/lib$ grep -rn random_id .
./ib/connection.rb:44:                   client_id: random_id,
./ib/connection.rb:179:        id = random_id
./ib/connection.rb:416:		def random_id

leads to the solution: random_id is also used to generate id's for the received-array, where messages arriving from the tws are stored.

   def subscribe *args, &block
      @subscribe_lock.synchronize do
        subscriber = args.last.respond_to?(:call) ? args.pop : block
        id = random_id

Then this experiment reveals the problem.
Modifiying random_it to

		def random_id
			puts SafeRandIdGenerator.generate
			rand 9999
		end

ans subsequent usage of the console
``'`
newdevel:~/workspace/ib-api/bin$ ./console

Got next valid order id: 14.

exploits that tws-messages went to only one received-array-entry. 

No wonder, that the application crashes.
