Check for Hurricane before checking stun immunity

[bricks]

I've been playing a fairly successful Tempest. The only gripe I've had is how often Hurricane fails to proc on bosses and certain mobs, very likely because they are immune to stun effects. Hurricane is a weak enough effect that I don't think it would be overpowered against bosses and other mobs, and it's nice damage-over-time for a build that focuses mostly on direct damage. I think that the target:canBe("stun") check should occur only when applying the daze, leaving the Hurricane effect to only check against spell save.
