discovery: avoid dropping remote heads hidden locally
An extra post processing was added to recognize remote heads that are hidden
locally as "common" instead of "unknown". However, this processing was
removing such hidden heads from the remote heads sets.
It had no impact because we used to pull phase information from all remote
heads.
This series will replace the phase pulling operation to a more efficient
process but requires the unmodified pulled set information.
