Broadcast schedule another time after filtering connection on rank 0

Only after rank zero does the filtering the schedule the well
definitions in there are guarateed to have no perforations to inactive
cells. Therefore we broadcast the schedule another time to publish
this to all processes.

Previously, we did the filtering locally on these processes bit that
did also remove perforations to cells that are active globally but
not locally. That seems very hard to work with when allowing
distributed wells.
