Bufixes: coin spawn and collect noise

Fixed a few bugs: coins were flashing on spawn, and their "collected" sound was a little delayed

The first was an issue with the animation player being played by code, and also by being set to auto-play 🤦‍♀️

The second issue wasn't really an issue at all, it was flagged off of a video that had a slight audio dysynch! Still, adjusted the point in the code when the sound plays just to be on the safe side
