rHGb4057d001760: merge: when rename was made on both sides, use ancestor as merge base
Summary

When both sides of a merge have renamed a file to the same place, we
would treat that as a "both created" action in merge.py. That means
that we'd use an empty diffbase. It seems better to use the copy
source as diffbase. That can be done by simply dropping code that
prevented us from doing that. I think I did it that way in
57203e0210f8 (copies: calculate mergecopies() based on pathcopies(),
2019-04-11) only to preserve the existing behavior. I also suspect it
was just an accident that it behaved that way before that commit.

Note that until fa9ad1da2e77 (merge: start using the per-side copy
dicts, 2020-01-23), it was non-deterministic (depending on iteration
order of the allsources set in copies._fullcopytracing()) which
source was used in the affected test case in test-rename-merge1.t. We
could easily have fixed that by sorting them, but now we can instead
detect the case (the TODO added in the previous patch).

I'll insert another patch with another fun test case before this patch soon

test-rename-merge1.t fails with this patch. Looks like there is one more instance of prompt which is not needed anymore. I didn't amend that in flight as I was not sure.

I'm pretty sure it's flaky for some reason. Augie also mentioned that that test failed on one of my patches. I ran it 100 times with different python hashes and it never failed for me. I don't know why it behaves differently sometimes. I'm not even sure it started failing with this patch. Does it fail consistently on this one for you? Does it pass consistently on @?

Oh, and note that --runs-per-test=100 will run the test 100 times with the *same* python hash.
