Spells: Riotous Health casted blocking Velious BP refresh

[evilkorn]

This appears to be a bug introduced recently because I don't remember running into this before. If someone has the casted version of Riotous Health you can not refresh that with the shaman Velious BP version of the buff even though they result in the same buff strength.

Steps to reproduce:
Cast Riotous Health on yourself
Click BP on yourself (using Spirit Caller's but doubt that is the main problem)
Result: Spell does not take hold
