rewind: make sure merge commits include files from p1 and p2

Otherwise rewinding a merge commit makes it lose all changes.

This fix populates `updates` argument of rewriteutil.rewrite() with parent
changesets. That argument is normally used for folding multiple changesets, but
in this case it's simply used to include files from p1 and p2. Usually,
rewrite() works fine using ctx.files(), but that function can return an empty
list when ctx is a merge commit.

This test file test the various messages when accessing obsolete
revisions.
