discovery: improve "note: unsynced remote changes!" warning

This message frequently caused confusion. "unsynced" is not a well established
user-facing concept in Mercurial and the message was not very specific or
helpful.

Instead, show a message like:
  remote has heads on branch 'default' that are not known locally: 6c0482d977a3

This message will also (when relevant) be shown before aborting on "push
creates new remote head".

A similar (but actually very different) message was addressed in 6b618aa08b6e.
