Abilities can't reference prefixed resource locations

[Apceniy]

Attempting to use prefixed resource locations in codec fields (for example, ability groups in "activate_ability_if" ability) results in the field (and if the field is mandatory, the whole codec) being invalidated.
After some code analysis, I think that this happens because of this line. Currently we have this:
result = new ResourceLocation(rl.result().get());
I assume it should be changed to this:
result = new ResourceLocation(str);
A couple of lines earlier we calculate str but the variable ends up unused, which is probably what should be used in place of rl.result().get() because the value of str also derives from it but then gets the prefix removed.
