Fix test failures on API 22

A SecurityException is thrown when using
AccountManager.addAccountExplicitly because the app doesn't have
AUTHENTICATE_ACCOUNTS permission. This bumps the Sdk required for the
failing tests instead of taking the additional permission since
AUTHENTICATE_ACCOUNTS isn't needed on API 23 and higher.

Test
ran GoogleContactsTests
