Investigate flakiness with tap() and enterText() on Android

[bartekpacia]

Occurs once in 10-15 tests on the login page in the customer project.

Reported by @jBorkowska.

Still occurs. Looks like this is caused by the keyboard obscuring the view.

Example log:

══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞════════════════════════════════════════════════════
The following PatrolActionException was thrown running a test:
Patrol action failed: enterText() failed with code NOT_FOUND (selector
UiSelector[CONTAINS_TEXT=Password, PARENT=UiSelector[CLASS=android.widget.EditText]] found nothing)

A possible workaround is to now show the keyboard when entering text - see #967 to learn more.

The bug is still there. I try to test the connection on an Auth0 page. Everything works fine, but sometimes it can't find the Continue button or can't write to a field. And this happens randomly.
This makes it impossible to test the application reliably. Sometimes tests don't pass when they should.
