  Fixup tests (thanks @celticminstrel)

Seems there were a few problems post-e46dfcc
- There was no need to use std::remove on a set, since the values are already unique (and std::remove
  doesn't work with a set anyway). We can just specify the value to remove directly.
- std::sort isn't supported and is redundant on a set - the values are already sorted.
