Clears the reference to the activity.

This method should be called in the onDestroy method of the calling activity to prevent memory leaks. It does not tear down AIDL: subsequent AIDL calls still work via the application context. For CommunicationType.INTENT, call initialize again with a live Activity before the next operation.

Do not use this method as a substitute for logout, and do not call it on every minimize (onPause/onStop) unless you are ready to initialize again.
