lokdialog: Trigger repaint on all opened dialog with invalidate

For now, temporarily trigger paints for all the opened
dialogs whenever a dialog invalidation callback is emitted. This solves
the problem for some of the dialogs where hard coded uno command, which
we are using as dialog IDs in GTV, doesn't match with the dialog id
contained in the payload of the invalidation callback.

With this SearchDialog, AcceptChangeTracking and few others are
responding well to mouse clicks and invalidate instantaneously while to
invalidate and repaint some other dialogs, one needs to refocus them.
