copies: get working copy parents from wctx, not dirstate, to make in-mem work
Before this patch, `run-tests.py test-rebase-conflicts.t
--extra-config-opt rebase.experimental.inmemory=1` would have some
lines that say "searching for copies back to rev 3" changed to
"... rev 1". I don't know of a better way of testing this patch than
doing that manually. There are many other differences, so we're not
ready to use #testcases syntax on the entire test-rebase-conflicts.t
yet.
