hgweb: make 'summary' work with hidden changesets (issue3810)

Since the 'summary' view used by e.g. gitweb and monoblue shows both a
changelog and a bookmarks list, the same changes are needed here as were
made to the 'changelog' and 'bookmarks' web commands (56ca4443a343 and
886936ecc21b, respectively).
