revlog: fix lazyparser.__iter__() to return all revisions (issue2137)

Previously, it only returned revisions that were in the revlog when it
was originally opened; revisions added since then were invisible.
This broke revlog._partialmatch() and therefore repo.lookup().

(Credit to Benoit Boissinot for simplifying my original test script
and for the actual fix.)
