FIX: fix two tree support bugs

Browse source 
1. hybrid(auto) on_buildplate_only option not working correctly because
parent is not set.
2. tree(auto) on_buildplate_only not working correctly because unsupported
branch isn't deleted completely. I add child to track the dangling nodes
and then delete nodes with no child.
