PolygonCollider2D doesn't adapt to shape when new SpriteShapeComponent is created.

Steps to Reproduce:
1. Open the "SampleScene" from attached Project
2. Drag and Drop "TestEmptyProfile" from Project window to Scene View.
3. Add PolygonCollider2D to the newly created game object
Observe Pentagon shape collider is formed.

Works Fine on SpriteShape Package Version: 1.0.4-experimental
Reproducible on SpriteShape Package Version: 1.0.10-preview.1

Note: SpriteShapeProfile is introduced from 2018.1.0
Polygon Collider 2D works as expected while using simple sprites.

Environment: Occurs on Windows 10, Windows 7, Mac OSX 10.13 & Mac OSX 10.12
