The biometric unlock initializeView() function is called every time the lockscreen is recreated. Since this normally happens when the device turns off, initializeView() was covering the backup lock so the backup lock is not exposed when the device turns back on. However, initializeView() is also called when lockscreen is recreated due to an orientation change. With this change, the show() call to cover the backup lock has been moved out of initializeView(), and the backup lock is now only covered when the screen is turning off, preventing the backup lock from being covered on an orientation change. This also includes changes to prevent biometric unlock function calls from occurring when SIM or Account unlock is in use. In fact, in any situation where we know FUL won't be used, we don't even construct it. This is not only more efficient, but it also cuts down on the possibility of errors where FUL is being used when it shouldn't be. Change-Id: Ie97761840df8de5701703d9b9b991726fb601064
