Fix mesh_snap_utilities_line crash when closing blender 

When the tool is active and the blender is closed, the `GizmoGroup` type
object is freed keeping some invalid RNA members.

This is probably an internal error, but for now just work around this
error by starting the object name with '_' since "RNA can't start with
a "_",".
