[empathy] Remove the name of an account once it has been deleted.

    Remove the name of an account once it has been deleted.
    
    This fixes a minor security issue where information about an account (its
    name) could be displayed after the point it was deleted. It only lasted
    until Empathy was quit. This patch ensures the name is scrubbed from Empathy
    immediately.
