Blackwing Lair, some fixes.

[geoburn]

Some fixes for Blackwing Lair:
* Razorgore the Untamed, need to have Spell Fireball Volley 22425 when is controlled by player (ytdb has the same spell1 and spell2).
* Vaelastrasz the Corrupt: The boss does not start the event because has a wrong gossip_menu_id, core is calling gossip_menu_id 21334 like you can see in: https://github.com/TrinityCore/Trini...aelastrasz.cpp line 36.
