Short description of error
When selecting a Bone Group Color set and then reverting it to default, the preview colors of the last color set remain in the UI.

Exact steps for others to reproduce the error
Create Armature, add a second bone. Enter Pose Mode, select both and add them to a new Bone Group. Select a different color set. The new colors appear to the right of the dropdown. Then select Default Colors again. The colors right of the dropdown stay unchanged but the bones in the viewport revert to the standard display color.

What it should do: when selecting Default Colors again, revert the preview colors to default as well.
