Mob-specific settings are not working

[Laike-Endaril]

The mob-specific settings to not seem to be working; defaults are always used instead.

All default settings for both vanilla and custom spawners seem to work fine, though.

Example test settings (I did other tests as well):
Vanilla Spawner Config > moblott > defaultvalues > xpMultiplier
0
Vanilla Spawner Config > mobloot > xpMultipliers
minecraft:blaze:100000

If you find a blaze spawner in a nether fortress, the blazes from it will drop 0 xp.

This also applies to the new settings from my PR. Details can be found here.
