tests: test more cases where a file got replaced by a copy

This adds a test where a file is modified on one branch and is renamed
onto another file in another branch. That should ideally be
automatically resolved (by propagating the modification to the rename
destination). Alternatively, it could be considered a modify/delete
conflict. It should at least not be automatically resolved by ignoring
the modification. However, that is what actually happens with the
changeset-centric algorithm since I broke it in b4057d001760 (merge:
when rename was made on both sides, use ancestor as merge base,
2020-01-22). Before that commit, it resulted in a modify/delete
conflict. The filelog-centric algorithm was broken already before that
commit.

Prepare the repository

  $ hg init empty
  $ cd empty
  $ touch ROOT
  $ hg commit -A -m "Root" ROOT

  $ touch a b c
  $ hg commit -A -m "Add A, B, C" a b c

Check the log

  $ hg log --config extensions.t=$TESTTMP/logexthook.py
