[MC-46648] /kill @e Kills Nearby Spectators

Executing the command '/kill @e' will kill nearby spectators.

To reproduce:
1.) Execute /gamemode 3
2.) Execute /kill @e

Or:
1.) Create a command block system that executes '/kill @e' at certain intervals.
2.) Stand nearby while in spectator mode.

Quite intended.
Specators == Players == Entities.

I see, I was under the impression that spectators were supposed to be unable to interact with the game at all.

Thanks for your time!
