narrow: add a test for linkrev computation done during widen

This new tests show that the linkrev computed and sent by the server might end
up being wrong during a widen operation.

+Since we have the same file conent on each side, we should get a limited number
+of file revision (and the associated linkrev).
+
+This these shared file-revision and the associated linkrev computation is
+fueling the complexity test in this file.
