test class.
BBCT Common Tests: Clean up FilterActivityTest subclasses

Remove FilterActivityTest#testOkButtonOnClickWithSetInputText() and
XxxFilterTest#setInputText(). These methods repeat the tests performed

Change minSdkVersion from 8 to 16 because DatabaseUtil#deleteDatabase()

event after selecting the player's position from the Spinner

Include team field in the comparison.
