Mobs stop being tracked after restart and lose their MM attributes
Summary
Describe the bug encountered in detail.
Steps to reproduce
Here is a config of one such spawner https://pastebin.com/Y89D0sR5 , you can see that the maxmobs is set to 3 yet after a restart it has 5 active mobs. It doesn't seem to spawn any more after more restarts, but it still does it once and it can overflow the spawners if they have higher amount of mobs to spawn. Version: 1.17.1 Paper git-paper-88 MythicMobs: Premium 5.0.0-snapshot-a0e23ea4
Current behavior
After a restart the spawners ignore spawned mobs, making them vanilla mobs (losing disguise, cmds not working on them etc.), and spawning more mobs in even if it's over limit of MaxMobs set.
Intended correct behavior
Mobs stay tracked and don't overflow the maxmobs limit.

Proposed fixes
Fix tracking mobs after a restart.
