discovery: properly exclude locally known but filtered heads
The conditional was a bit too narrow and produced buggy result when a node was
present in both common and heads (because it pleased the discovery) and it was
locally known but filtered.
This resulted in buggy getbundle request and server side crash.
This test file aims at test topological iteration and the various configuration it can has.
$ cat >> $HGRCPATH << EOF
> [ui]
> logtemplate={rev}\n
> EOF
On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
