Jeremy Goldman 899eb7282d TopLevelStoragePreferenceControllerTest converted to JUnit
Helper function composed to return thread future, to guarantee
concurrent function finishes before test condition is checked.
Additionally a @VisibleForTesting helper function is used rather than
robolectric reflection helpers to set a class variable.

Test: atest -c TopLevelStoragePreferenceControllerTest
