Omitted extraneous test.
New Tests for BasicOnceUxSampleApp

## Rationale

Beginning to add more robust testing for the Android Native Player's OnceUx plugin and Basic OnceUx Sample app.

## Files Changed

BasicOnceUxSampleApp/src/androidTest/java/com/brightcove/player/samples/onceux/basic/test/MainActivityTest.java
* setWifi(false) command disabled to stop the test from crashing (SDK-156)
* changed strings to objects to stop classCastException
* testing for null instead of !null to avoid nullPointerException crashing the test
* changed to turn wifi back on when test succeeds, but is delayed by a countDownLatch
