[nautilus-share] Allow actions to be undone without closing window

    Allow actions to be undone without closing window
    
    Previously, after clicking "Create Share" or "Modify Share", it is impossible
    to undo the action, i.e. remove the share after creating it, or to re-add the
    share after removing it. This commit fixes that.
