Fix blank screen when launching controls activity

It was possible to attempt to launch a non showWhenLocked activity
over the keyguard by passing the wrong value into the
activityStarter. In addition, the existing code would trampoline
activities which produced a bad opening animation.

Directly launch the correct activity, and also set the
showOverLockscreenWhenLocked flag to the correct value to ensure the
animation runs properly.
