Rebuilding a mesh, using the job system to bake the collider, then setting the mesh, results in a double collider bake



To reproduce:
1) Open the attached project and scene
2) Open up Profiler, and enable Deep Profile
3) Play it, then pause it after a few frames come in
4) Select the current frame in Profiler
5) Search for sharedMesh in Hierarchy

Expected: The collider is baked once
Actual: The collider is baked twice

WORKAROUND: Do not reuse the Mesh instance for now. Every time you bake, that should be a new Mesh instance.

Reproduced in 2020.1.0a12, 2019.3.0b11, 2019.3.0a9 (when the feature was introduced)
