When using a Physics Asset with 4 or less physics bodies the flag for Start Awake cannot be disabled, even if unchecked, when Simulate Physics is set to true.

I've attached a project with assets from the engine content folder that can reproduce this using the TutorialTPP character and the SkeletelCube mesh.

SkeletelCube had to have a physics asset generated, which has two physics bodies.

Confirmed in:
4.10 Binary Release
4.11 Release CL-2781072
Dev-Physics CL-2794504

Steps to Reproduce

1. Open attached project
2. Press Play or Simulate

If creating from scratch:
1. Create or import a skeletal mesh with any number of bones
2. Create a physics asset and make sure that it has 4 or fewer physics bodies
3. Place in the world
4. Set the asset to Simulate Physics with Start Awake Disabled
5. PIE or Simulate

Expected: With Start Awake disabled the asset should not start awake

Results: Asset starts awake regardless of the option being disabled.
