Assigning a new Collision Channel to an already fractured Destructible will cause a crash

The editor will crash when assigning a new collision channel to an already fractured destructible mesh.

Tested in:

4.13 CL-3106830
4.14 Dev-Main CL-3109838

1. Create a Destructible and in it's DM properties fracture it and then enable Impact Damage.
2. Drag the Destructible into the level and set it to Simulate Physics while above the the floor mesh.
3. Open the Level BP and reference the Destructible
4. Recreated the setup from the attached image (LevelBP.png)
5. PIE
6. After the destructible has fractured press assigned Key (F from my image)

Regression: No

Results: The editor will crash.

Expected: The editor should not crash.
