Update Hvac to remove the self register or ui components with their controller

They were being removed from the status bar when the device was un-provisioned
due to a false state change. There was also an issue where the background
tried to animate before it was on screen causing an exception

Bug:110105682
Test: run on bench or test hardware of the outside kind
