Reimporting a static mesh will reset multiple properties in the Static Mesh Editor

When reimporting a static mesh settings that have been changed in the Static Mesh Editor will be reset to the defaults.

1. Open UE4
2. Export any static Mesh (I created a copy of the cube in Engine Content)
3. Open the Static Mesh Editor
4. Change some of the settings like Cast Shadow, LPV Bias, or LOD Group.
5. Reimport the Mesh by locating it in the Content Browser and right-clickign > Reimport or using the Static Mesh Editor Menu > Asset > Reimport

Regression: No

Results: Settings in the Static Mesh Editor will be reset when mesh is reimported.

Expected: When using the reimport option the settings should be honored.
