entity looks at its casting target when casting an event with behavior.send_event

Verification builds: 1.16.20.50 Release build

Summary: When casting an event with the "minecraft:behavior.send_event" component, the entity rotates to face the entity it sends the events to.

Impact: This prevents using this handy component on custom entities that are meant to be immobile.

Reproduction steps:

1. create the world attached to this report
2. notice how the chairs entities rotate to face the player

Expected result

The entities don't rotate.

Actual result

The entities rotate. Notice how they rotate: once per second (corresponding to the "cooldown_time" of the component), for a slight moment (corresponding to the "cast_duration" of the component).
