If an SQL query doesn't specify any ordering, avoid the implicit sort
...
that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

Fixed #8354 : the MySQL backend no longer raises a cryptic error. Instead, it raises a less-cryptic error. Obiously this isn't a perfect solution by any means, but it'll do until we can revisit timezone handling in the future.

This effectively reverses the change in [7798]. It was proving too difficult to
successfully manage all the side effects here and provide a satisfactory
solution for everybody. Many thanks to arne, Martin von Löwis and, particular,
Karen Tracey, for doing a lot of research and proto-patches here to establish what was possible and practical.
This is backwards incompatible if you were relying on the behaviour after
[7798]. The docs have been updated to indicate the solution.
