Do not filter connections on the schedule of the loadbalanced grid.

It would remove perforated cells from wells that cross the local
domain's border. That would make it impossible to figure out the
first connection. In addition we would not be able to check that
the connections exist (as rank 0 would have the complete information
-> inconsistency).
