Handle when sim state indicates that it is absent

We want to update the sim state the view mediator when the sim state
indicates that it is absent. When we disable the esim, we want to be
able to update the sim state to indicate that we no longer have secure
sim pin when we swipe to unlock. Additionally, we want to ensure that
mPendingPinLock is set to false so that we do not show keyguard again
after dismissing.
