Can't disable gravity for skeletal meshes

When replacing a static mesh with a skeletal mesh for bone animations, it falls to the ground. Even though gravity is disabled on the skeletal mesh.

Changing the gravity scale to 0 is a work around for the issue.

1. Create a new Flying template
2. Replace the static mesh in the UFO with a skeletal mesh for bone animations
3. Disable gravity on the skeletal mesh
4. Observe that even though gravity has been disabled, the mesh still falls
