dagop: minor python optimization to `headrevs`

Less lookup and less function call never hurt. This provides a small speedup
on various run of the 'heads()' revset. This also buys back some of the slow
down we observed in the previous changesets for single value lookup.

Performance number:
0) before dagop.headrevs usage
1) after dagop.headrevs usage
2) after this change

Command works on an empty repo

  $ hg show work

Single draft changeset shown

Even when it isn't the wdir

Single changeset is still there when public because it is a head

  $ hg phase --public -r 0

A draft child will show both it and public parent

  $ hg -q up 0
