Remove starting animation in BaseInstrumentationTestRunner.java

Added TargetContext.java: Extending Context.java, TargetContext.java overrided startActivity
method executing with activityOptions to disable launching Animation.

Modified BaseInstrumentationTestRunner.java: changing startActivitySync(intent) by overriding getTargetContext
method and convert Context to TargetContext.
