Bug Building with "remove trait" effect throws burst error

To reproduce :

- Create new project (Unity 2020.1.12f1).
- Add AI Planner 0.2.4-preview.3.
- Create semantic trait "TraitToRemove"
- Create ai planner action "RemoveTrait" with a single parameter containing TraitToRemove
- Create an Object Modified -> Remove Trait effect on RemoveTrait
- Create ai planner problem "RemoveProblem" containing RemoveTrait
- Run Semantic -> Traits -> Build
- Run Ai -> Planner -> Build
- Run File -> Build And Run generates
