Don't consider a group to be on a copper layer. 

Its members can be on copper layers, but the group itself isn't on any
layer.

Also fixes a bug where we were trying to clone TRIANGULATED_POLYGON::TRI
shapes as indexable sub-shapes.  (The TRI only has indexes into its
parent, so cloning it will only result in segfaults down the line.)

Also fixes a bug where we weren't including copper items inside groups
when checking footprint net ties.
