[TW] Core/Spell: Druid T10 Resto 4PC Rejuvenation

- Should not apply to targets that already have rejuvenation cast by
that player
- Should select lowest health player in group
- Not sure on attr change it works though. All the spells with this attr
are healing spells that take damage from the trigger spell or are % of
health that shouldn't have bonuses applied but this is the only one that
healing bonuses are being applied to. Maybe overlooking something.
- still bug with it stacking should be fixed in DB
