tests: demonstrate how evolve loses transitive copies when interrupted

Let's say `b` has been renamed to `c` in commit A and then renamed
to `d` in commit B. We now modify A in a way that will cause a
conflict when we evolve B. `hg evolve` will now stop and let the user
resolve the conflicts, but it will have lost the copy information in
the working copy (should still be c->d).
