targetself=true does not work with EIR

Summary

the "targetself=true" filter for targeter does not work with the EntityInRadius targeter. It does work as intended with the PlayerInRadius targeter however.

Steps to reproduce

Just created a skill with this line : - potion{type=POISON;duration=200} @EIR{r=5;targetself=true} And i do not get affected by the skill. However, if i change the targeter to @PIR{r=5;targetself=true}, it works.
