discovery: prevent crash on unknown remote heads with old repo (issue4337)
When a remote is not capable of the `branchmap` wireproto command, we denote
incoming heads with None. This leads to a crash in the code in charge of
displaying the list of unknown remote heads.
We now properly detect this case and display a shorter message in this case.
The reason for this `set([None])` value is now documented.
