Removing ssh keys

[kulajk]

If a user has several ssh keys, removing one of them does not remove it from set on target machine.

I noticed this recently as well, had a user with a new ssh key to replace an old one. After running the role it appended the new key into .ssh/authorized_keys but didn't remove the old one, even though it was removed from the var file for that user.
