treediscovery: always return all remote heads
Old discovery only returned incoming heads, not all of them (for
changegroupsubset). New discovery must always return all of the remote heads
(for getbundle). I failed to properly adjust treediscovery in cb98fed52495
when introducing setdiscovery.
The actual observable problem was 'remote: unsynced changes' when trying
to push a cset on one named branch to a server with a new cset on another
named branch. This scenario is now tested in test-treediscovery.t.

"""create a new shared repository
Initialize a new repository and working directory that shares its
history with another repository.
.. note::
using rollback or extensions that destroy/modify history (mq,
rebase, etc.) can cause considerable confusion with shared
clones. In particular, if two shared clones are both updated to
the same changeset, and one of them destroys that changeset
with rollback, the other clone will suddenly stop working: all
operations will fail with "abort: working directory has unknown
parent". The only known workaround is to use debugsetparents on
the broken clone to reset it to a changeset that still exists
(e.g. tip).
