Apparently we forgot to handle schematic connectivity changes when redoing
undone changes. The same connectivity update logic that was added to the
commit object is now used in SCH_EDIT_FRAME::PutDataInPreviousState().
Please note the granularity of connectivity rebuilds on schematic object
property changes is at the object level which is overly aggressive. This
means that connectivity rebuilds will happen when connectivity changes
that have nothing to do with and objects connectivity are changed. Until
objects can handle their own connectivity state, this will have to suffice.
