py3: fix test-convert-svn-sink.t
In cases where the root commit is empty commit, None will be returned as
parents. This was implemented by
2c13e91ede6e.
This breaks test on py3 because `b'%s' % None` does not work. It does not matter
whether we return `None` or `'None'` as we skipped converting to svn step by
doing an early return. So let's return `'None'`.
I tried to patch all the users to convert `None` to `'None'`, but there were
more users than I expected. I hit 3 of them and decided to fix it this way
around.
