summary: make "outgoing" information sensitive to branch in URL (issue3829)

Before this patch, "outgoing" information of "hg summary --remote" is
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 looks head revisions, which are already detected by
"hg.addbranchrevs()" from URL, up against local repository, and
invokes "discovery.findcommonoutgoing()" with list of them as
"onlyheads" to limit calculation of outgoing revisions.
