Hash-order independent tests
`tests/testhttpserver.nim`(850, 12) and (852) fail with a new string hasher because they assume a specific order.

Any chance you guys can do something like @Vindaar did [here](https://github.com/SciNim/Datamancer/pull/69) in the next few days?  Really just add a `.sorted` and put the `@[]` in sorted order.
