function image_effects_image_style_presave in Image Effects 8

Same name and namespace in other branches

1. 8.3 image_effects.module \image_effects_image_style_presave()
2. 8.2 image_effects.module \image_effects_image_style_presave()

Implements hook_ENTITY_TYPE_presave() for image_style entities.

This hook checks if the image style that is being saved contains any aspect switcher effect that refers to the image style itself. If so, this is a circular reference and we should raise an exception.
