DB/Conditions: Injured rainspeaker oracle

Rewrite of conditions I used in https://github.com/TrinityCore/TrinityCore/commit/0c1587cc916de846eedf3ccf48f80caf053f427b for a few things I overlooked when I writ original conditions, like fix the issue where someone without quest could click gossip menus and select the gossip menu to get the injured oracle to his feet and then make it impossible to turn in just following orders, gossip is now only displayed if player has or needs to take quest or select gossip option to start event.

conditions to prevent gossip option been selected to start wp while has feign death.
