merge: add test with conflicting file and remote directory rename

Changset 88629daa727b (merge: demonstrate that directory renames can
lose local file content, 2014-12-02) should clearly have added the
reverse version of the test: where the remote side renamed a
directory, added a new file in that directory, and the local directory
added a conflicting file in the source directory. Add such a test now,
and also touch up the ones already added slightly (e.g. 'local' was a
stupid value for content that can be on either side of a merge).
