Fix possible-nil return type of EventPermissionStrategy#getEntityType (#1278)

* Update pubspec.yaml

* Update CHANGELOG.md

* Fix return type of EventPermissionStrategy#getEntityType

This method is causing a compilation warning: -Wint-conversion.

Even ignoring the warning, the nil value would not be tolerated and is never actually returned.
