Fix/workaround T50677: Shrinkwrap constraint don't get updated when target mesh gets modified

Do a "full" update on leaving sculpt mode, so we are sure scene will be brought
to a consistent state.

Ideally we'll only do that when there are objects which depends on geometry
without re-calculating self geometry, but that's a bit tricky currently.
