Drop overlap with WildStacker

[CoolLord22]

Describe the bug The WildStacker plugin overrides the drops defined by OtherDrops. If, for example, a user drops NOTHING with OtherDrops, WildStacker's loottable of original drops will override, and give the default drop instead.

To Reproduce Steps to reproduce the behavior:

1. Install WildStacker 2.7.1 and OtherDrops (latest)
2. Define a drop in OD to drop NOTHING
3. Test the drop
4. See default drop instead of nothing

Expected behavior By default, there should be no drop if the defined parameter is NOTHING.
