Destroy and reinflate bouncer before showing

Due to various bugs and settingns changes, it makes sense to entirely
refresh the bouncer view before showing. This should significantly
reduce the number of incoming bugs where bouncer is not showing or is
not responding to settings changes.

**Ensure that password view shows by ensuring that mDisappearAnimation running is set back to false.
