Enable ImeTracker onProgress in SimpleIme tests

This enables logging of onProgress calls for the ImeTracker phases.
Additionally enables re-using setShowImeWithHardKeyboard in tearDown.

Also removed some unnecessary eventually calls in configuration change
tests, as these were directly modifying the Configuration object and
calling a method that checks its value, so it couldn't have any delays.
