cleanup: make some improvements to group moderation test

- We no longer assert peer roles in the mod event callback
because this causes an issue with the new events implementation,
which triggers the events after all the packets from the
current tox_iterate() are processed, rather than as the
packets are received. These checks were superfluous and shouldn't
reduce code coverage.
- A moderator now sets the topic before the founder kicks him in
order to increase internal code coverage.
