rebase: fix for hgsubversion

5c25fe7fb1e broke something in the hgsubversion test path, causing it raise an
abort (Abort: nothing to merge) during a perfectly good rebase. I tracked it
down to this change. It's probably not hgsubversion related.

I suspect that using the same `wctx` from before the initial update causes
problems with the wctx's cached manifest property. I noticed we also sometimes
stick random gunk on the wctx object in other places (like in `copies.py`) so
it's probably best to reset it for now.

The line I added before was actually useless since we don't pass wctx to the
initial `merge.update`, so it defaults to `repo[None]`. So I just removed it.
