    objects: Fix repr_key for OpenWith and SourceLeaf
    
    And OpenWith does not need to be pickleable anymore.
    
    If the OpenWith (default) action is now resolved by reference, it will
    always find the *current default* open with action. Which can be
    expected in a way. If the user wants to save an absolutely specific
    trigger, you should use the Open With.. (any) action.
