Don't re-add deleted netclass assignments in incremental connectivity 

Ensures that if moving or deleting a netclass directive label, the
netclass on the previously-assigned net doesn't have the stale
netclass re-applied.

Cherry-picked from 0826c10a20

(Along with prior connectivity cherry-pick...)
