Unless there are no published tracks, declare connected on primary PC
connected.
Streamlining this a bit. A bit of history
- With original migration, migration complete was declared on all tracks
published.
- When muted tracks has to be migrated, a publish is synthesised for
muted tracks, but migration complete did not wait till publisher peer
connection connected.
- A few weeks back, those paths were merged and all cases were changed
to use synthesised publish.
- Previously the completion point was different between muted and
unmuted tracks. And with the change to treat everything like a muted
track, completion point changed.
Change it so that if publisher PC is expected to be active, wait for it
to be connected before declaring migration complete.
