[GAMEPLAY] Hextech Annie hp bar disappears when going invulnerable

Anytime a person using the hextech annie skin goes invulnerable their hp bar completely disappears instead of going golden. To recreate:

1. Annie uses Zhonya's, or gets hit by any other invulnerability spell (kindred r, bard r)

It is extremely hard to realize where an Annie is in a teamfight when her hp bar just completely disappears making it hard to manage a teamfight around an invulnerable annie
