[gitg] Move config destruction to dialog finalize

[Jesse van den Kieboom <jessevdk src gnome org>]

commit ff83aa6ffa7eb941343d2d9a41a5f106bec60e7a

    Move config destruction to dialog finalize
    
    This fixes a problem when closing the dialog while one of the config entries
    has focus. The config object would be destroyed in dispose, before the
    focus-out callback had been called.
