Skip 'namespace' compound nodes
Skip 'namespace' compound nodes

When trying to get the fully qualified name as if there is a 'namespace'
compound node in the node_stack there will also be a 'compounddef'
'namespace' node in the stack.

We need to compounddef node as sometimes the 'compound' node isn't
there.
