copies-tests: add a case where with merge with an overwritten files

This is similar to the BF/FB case, but in this case, the other branch updated
the file. So an actual merge happens and the two "independant" file history has
to be merged.

- one with change to a file (d)
- one overwriting that file with a rename (from h to i, to d)

Merge:
- one with change to a file (d)
- one overwriting that file with a rename (from h to i, to d)

This case is similar to BF/FB, but an actual merge happens, so both side of the
history are relevant.

Note:
| In this case, the merge get conflicting information since on one side we have
| "a -> c -> d". and one the other one we have "h -> i -> d".
|
| The current code arbitrarily pick one side
