[1.11] nearest_attackable_target does not select invisible entities.

Verification Build: 1.11.0.5 RC1

Partner Rank: 1

Summary:
The nearest_attackable_target behavior no longer targets entities with the invisibility effect, even though it used to.

Impact:

This is a behavior regression which does not respect format_version and therefore could have unintended consequences. It also breaks an upcoming map which has already been accepted and is waiting to release.

Repro Steps:

1. Create a new flatworld and a behavior pack with the attached files.
2. Place down a repeating, always active command block with the command: /effect @e[type=rabbit] invisibility
3. Summon a zombie and a rabbit a few blocks apart.

Observed Results: 

The zombie does not more towards the rabbit.

Expected Results: 
The zombie moves towards the rabbit, as the rabbit is the subject of its nearest_attackable_target component.
