Run tests broken on R- only on S+.

These tests were broken by ag/16425947 - the CL adds a call to shouldRestrictStorageAccessFramework, which uses PackageManager#getApplicationInfo, which is executed during the 2 tests ignored. However, the tests are unit tests and use a mock PackageManager, so we hit NPE.
