Core/Scripts: fix Tenacity Aurascript (target is null on UpdatePeriodic)

- also aura amount increases with stack so we lose spellid info, calculate it from basepoints directly
- aura should be SPELL_AURA_MOD_HEALING_PCT instead of SPELL_AURA_MOD_HEALING_DONE_PERCENT (ie taken instead of done, confusing names)

(cherry picked from commit bc2a4c816d6dc893b9b0c8d5bf0a15fe085506c5)
