rebase: fix crash with in-memory rebase and copies

When using regular on-disk rebase, filectx.markcopies() calls to
dirstate.copy(), which happily records the copy. Then it's simply
ignored if it doesn't matter for the commit (as in the test case I
added in the previous patch). Let's do the same for overlayworkingctx.
