[MC-114683] Moving minecarts or boats collide with players / mobs even if collisionRule disables collision

The bug

Moving minecarts or boats collide with players or mobs even if the collisionRule of the minecart's or boat's team prevents collision. It only disables pushing a stationary minecart or boat.

How to reproduce

Create a team.
```
/team add testTeam
```
Set the collisionRule option to for example never.
```
/team modify testTeam collisionRule never
```
Place a minecart on powered rails which will later move the minecart towards you (for example as seen in the screenshot).
Make the minecart and yourself join the team.
```
/team join testTeam @e
```
Make the minecart move towards you.
→ You will see that the minecarts stops in front of you, but you cannot push it

Code analysis

Based on 1.11.2 decompiled using MCP 9.35 rc1

The methods of boats and minecarts overriding net.minecraft.entity.Entity.getCollisionBox(Entity) do not test if the entity they are returning a bounding box for, can be collided with.
