Some entities on team harm teammates when they explode when friendly fire is false

Per @unknown's comment on MC-46956, I'm making a new report for this.

Entity explosions harm teammates, when friendly fire is false

Steps to reproduce:

1. /team add TestTeam

2. /team modify TestTeam friendlyFire false

3. /team join TestTeam

4. /summon creeper ~ ~ ~ {Team:TestTeam,Fuse:0s}

5. notice how you take damage from the explosion

Affected entities:

• Creeper

• Wither

• End Crystal

• TNT

• Minecraft with TNT

Expected result:

Friendly fire is respected and their explosions cannot hurt teammates.
