Title: Core/GOs: When unlinking Fishing Bobber from player to prevent despawning, unlink from spell as well to prevent removing unwanted auras

Solves that issue where if you try to fish while your last cast just failed, your new channeling is interrupted but your new boober doesn't fade. Which gets annoying later on.
