Quest A Spirit Guide (Issue 4028)

Cleaned up replacement to the PR https://github.com/TrinityCore/TrinityCore/pull/13590

Breakdown of changes from THIS pull request:

 - Ensures rep adjustment buff is always applied (overrides evade, implements existing evade + re-apply buff)
 - Removes un-owned ravagers with incorrect faction from DB (the correct ones are spawned with their masters without the DB entries)
 - Create some extra steps in the wolf's waypoints in order to generate some AI events for the Ryga NPC. I think it's a bit of a dirty solution, but it seems to work with minimal changes.
 - Created RP series of events with Ryga NPC and Ancestral Wolf Spirit (Ryga Kneels, talks to wolf, then returns to spawn position after around a minute).
Proper sql:

```sql
DELETE FROM `creature` WHERE `id`=19461;
DELETE FROM `script_waypoint` WHERE `entry`=17077 AND `pointid` IN (51, 52);
INSERT INTO `script_waypoint` (`entry`, `pointid`, `location_x`, `location_y`, `location_z`, `waittime`, `point_comment`) VALUES
(17077, 51, 519.146, 3886.7, 190.128,10000, 'RYGA_WALK'),
(17077, 52, 519.146, 3886.7, 190.128,1000, 'RYGA_RETURN');
```
