Music Trigger IPersistentTriggerData Crash (and more!) Fixer

Fixes the IPersistentTriggerData crash in Music Triggers v6. It was stated this issue will not fixed in v6 but in v7.

If you want a feature, to report a bug, or request a port: @ me in my Discord Server! GitHub works too but I rarely check that.

As of 1.0.1 this also fixes a ConcurrentModificationException crash with ServerTriggerStatus when accessing SERVER_DATA
