Added NoPlayTest, Tweaked MainActivityTest for OnceUX plugin

* int progress added as a way to definitively determine Playhead Position for Logs.
  * Progress event added in the setup method to allow all tests in MainActivityTest access to it.
* Tweaked testHideSeekControls in MainActivityTest.
* Removed programatically skipping ads.
* Added play event emitters to each test in MainActivityTest.
  * Remedied issue with wifi not turning back on for testAdDataReady in the MainActivityTest class

Are these progress positions significant? Should they be defined as a constant?
