[gimp/metadata-browser] app: fix GimpContainerTreeView name editing so it always works the same

[Roman Joost <romanofski src gnome org>]

commit cf506fc322e15ce5b43433afd5c8dd9f8843d9a4

    app: fix GimpContainerTreeView name editing so it always works the same
    
    no matter how editing was started (double click, keyboard activate, F2).
    
    Connect to "editing-started" of the name cell and set the object's
    real name directly on the GtkCellEditable, instead of trying to hack
    around in the tree store before the actual editing starts.
