histedit: make "hg histedit" sensitive to branch in URL

Before this patch, "hg histedit" are not sensitive to the branch
specified in the URL of the destination repository, even though "hg
push"/"hg outgoing" are so:

Invocation of "discovery.findcommonoutgoing()" without "onlyheads"
argument treats revisions on branches other than the one specified in
the URL as outgoing ones unexpectedly.

This patch specifies list of head revisions, which are already
detected by "hg.addbranchrevs()" from URL and looked up against local
repository, as "onlyheads" to "discovery.findcommonoutgoing()" to
limit calculation of outgoing revisions.
