Explicitly re-show rather than reset keyguard if we're not interactive.

Showing the keyguard while not interactive should only happen
during race conditions involving locking and unlocking
simultaneously, where we want to make sure we end up locked.
"Resetting" is a short-circuit to just reset the lockscreen
views if we are asked to show while already showing. If we
are asked to show keyguard while not interactive, even if we
think we're already showing, we should not short-circuit and
instead fully re-show the keyguard to ensure we end up in the
correct state.
