Before this commit, pyEnv.currentPartnerId and pyEnv.currentUserId
were not properly sync with userService.
This is not a big deal with current tests in discuss, as they do not
rely on userService. However, any test that do will likely fail.
This commit fixes the issue by imposing the `partnerId` and `userId`
in userService to the same as used in `pyEnv`.
We don't do the other way, because we must know the partner and user
before making the `env`, so at the time of creation of `pyEnv` from
`startServer`.
