Static getters in ComponentList.gd don't work with respawning entities

Description:
While working on the respawn functionality of the enemies the static getters registrations show a lot of errors and warnings when an enemy respawns.

E 0:00:50:0355   ComponentList.gd:50 @ register_component(): Attempted to assign an invalid (previously freed?) object instance into a 'TypedArray.

I've now disabled/commented out the static getters as they are not used anywhere yet.

Should be fixed.
