CallFeaturesSettingTest: Solves failing test case

Solves failing test case in CallFeaturesSettingTest that was introduced
by patch:
730453920d9ca71b357abcc5fa058365ab6635ba

Solved by using a real Context which is obtained with a call to
InstrumentationRegistry.getTargetContext(). This allows
SubscriptionManager.getResourcesForSubId() to complete successfully.
