ItemStackMixin#addUnusableTooltip breaks Polymer's server side tooltips

https://github.com/apace100/apoli/blob/1.19/src/main/java/io/github/apace100/apoli/mixin/ItemStackMixin.java#L55

This mixin breaks (otherwise fully working on server) getTooltip method.

Ideally that mixin should be either limited to client-only or be made server compatible.
