snapshot: fix line order when skipping over empty deltas
The code movement in 37957e07138c introduced an error.
Since 8f83a953dddf, we discarded some revisions because they are identical to
their delta base (and use that delta base instead). That logic is good,
however, in 37957e07138c we mixed up the order of two line, adding the "new"
revision to the set of already tested one, instead of the discarded one. So in
practice, we were never investigating any revisions in a chain starting with
an empty delta. Creating significantly worst delta chain (eg: Mercurial's
manifest move goes from about 60MB up to about 80MB).

==================================== Testing head checking code: Case D-1 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category D: remote head is "obs-affected" locally, but result is not part of the push TestCase 1: remote head is rewritten, but successors is not part of the push .. old-state: .. .. * 1 changeset branch .. .. new-state: .. .. * 1 changeset branch succeeding the old branch .. * 1 new unrelated branch .. .. expected-result: .. .. * pushing only the unrelated branch: denied .. .. graph-summary: .. ..
