There should no be two the same labels with the same name. After adding some tasks and assigning labels to them, there are two the same labels to filter by. They should be merged automatically. Labels should be also automatically formatted so the first and last character should not be a whitespace.

How to reproduce:

1. Add some task
2. Mark task as done
3. Unmark task as not done
4. Task in calendar tab is under "Finished that day" category

Expected result

Task should not be under "Finished ..." label

After switching tab, back button stops working. To make it work again user have to open task form.

Sometimes after e.g. device orientation change keyboard appears, although no input is visible

All tasks that contain some of selected labels in filter should be visible. Now only tasks that have all selected labels assigned to it, are visible.

Clicking on pushup notification doesn't redirect to the app.
