move key-handler prompts to the right bar (#481)

this makes it more consistent with e4fceab by moving the key-handler
related messages to the right side as well.

additionally this fixes a regression introduced by 3659361 where the
left statusbar would remain at "Running key-handler..." if the image
didn't change.
