This was to catch duplicate emissions for PropagateDirectory but we
don't emit this signal anymore from there.
This fixes a warning about PropagatorJob not being a registered metatype.
This reverts commit fe42c1a818.
Now that we have a separate list for files that could not be synced,
we can make sure that it only shows entries for files that are still
not in sync with the server. This allows the user to treat this list
as action items in order to get everything synced, including the
blacklist.
Simply remove the keep-errors logic that was used when the lists were
merged to achieve this result.
Because that's what's going on. A job can 'complete an item' or 'finish'.
Note that several jobs could complete the same item: a new directory
will complete on the PropagateRemoteMkdir and the PropagateDirectory
jobs.
Previously, PropagateDirectory jobs didn't emit the completed() signal.
Now that they do, we need to make sure to not add extra lines to the
protocol widget for them.
To accomplish that, the jobCompleted() signal now also contains the job
that completed the item.
