Migrate Telecom tests to JUnit4

Change all tests to use AndroidJUnitRunner instead of
InstrumentationRunner.
TelecomTestCase no longer inherits from AndroidTestCase.
Update the lite_test_telecom script to use JUnit4.

This allows Telecom tests to use modern JUnit4 features. Refactorings
along those lines will be in subsequent CLs.
