Stop apps with Storage Managers from launching activity when disabled

Browse Source 
An app with a storage manager would be able to launch Manage Storage
from application settings, but when the app was disabled, the
activity would be null.

Test: In order to properly unit test this function, a large redesign is 
needed in this class, and is outside the scope of this bug.
