Depsgraph: tag relations for update when aterial slots changes

New dependency graph puts materials to the graph in order to deal with animation
assigned to them and things like that. This leads us to a requirement to update
relations when slots changes.

This fixes: T49075 Assignment of a keyframed material using the frame_change_pre handler
                   doesn't update the keyframe using the new dependency graph
