Players on Visitor mode should not attract mobs

Players set to Visitor mode on a Bedrock Realm, with default settings, have the unwanted ability to attract mobs, allowing malicious visitors to drag creepers to builds and cause damage.

Steps to Reproduce:

1. In a realm (default settings) with multiple players connected, have the realm owner set a player to Visitor status
2. Wait until night
3. Ask the Visitor to go near spawned creeper

Observed Results:
Observe the creeper (or all hostile mobs) can target and attack the Visitor. Creeper will blow up and damage area around the Visitor as well as killing them.

Expected Results:
Hostile mobs should not see or target the Visitor.
