"ignore_lighting" not working in render controllers.

Partner Rank: 3**
Verification builds: 1.12.0.27

Summary: Using ["ignore_lighting": true] in any entity's render controller doesn't work anymore. For example, a charged creeper's armor doesn't glow anymore. This bug is still happening in 1.13.0.2_beta_rc0.

Impact: Entities don't ignore lighting when they have "ignore_lighting" set to true.

Repro Steps:

1. Add ["ignore_lighting": true] to any entity.
2. Summon the entity.

Observed Results: The entity doesn't ignore lighting.

Expected Results: The entity should ignore lighting.

Screenshots/Videos attached: Attached pics of a custom entity with "ignore_lighting" set to true in '1.11' and '1.12'.
