Test failure with hashable 1.3.1.0

It passes with hashable 1.3.0.0 and others unchanged.

Snap.Util.CORS.Tests:
  CORS/simple: [OK]
  CORS/options: [Failed]
Header "Access-Control-Allow-Headers"
expected: Just "X-STUFF, Content-Type"
 but got: Just "Content-Type, X-STUFF"

This is due to the hash being unstable. I've sent a PR repairing this test, but in general, we shouldn't rely on any order we don't ourselves enforce.

Reference about hash instability.
