    gkr: Don’t update key description if it doesn’t change
    
    If the user right-clicks in the ‘Description’ entry in the item
    properties window, without changing the description, their text
    selection will be dropped. This is because Seahorse is trying to update
    the item description in the background, as a result of the entry losing
    focus.
    
    Avoid trying to update the item description if it has not changed, which
    will cover most cases of the user right-clicking.
