obsolescence: add test for the "branch replacement" logic during push, case D7 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 changeset adds test for the improved "branch replacement" logic introduce in an earlier commits. This tests initially lived in the evolve extensions. Since we now have the code handling this logic in core, it make sense to have the tests in core too. See inline documentation for details about the test case added in this changeset.

+====================================
+Testing head checking code: Case D-7
+====================================
+
+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 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset
+
+This is a partial push variation of B6
+
+.. old-state:
+..
+.. * 1 changeset branch
+..
+.. new-state:
+..
+.. * old branch is rewritten onto another one,
+.. * The rewriting it again rewritten on the root
+.. * the new version is then pruned.
+..
+.. expected-result:
+..
+.. * push allowed
