[gnome-photos] application, preview-view: Remove app.undo-current

[Debarshi Ray <debarshir src gnome org>]

    application, preview-view: Remove app.undo-current
    
    We are not planning to offer the ability to undo each single edit.
    Instead we allow reverting a series of edits. This makes the
    app.undo-current entirely useless and, in fact, it is not used at all
    at the moment.
