Expand/Collapse Icons Should Not Render When No Children Nodes Are Available

[pkmccaffrey]

Currently, if a given tree node has no children (but the nodes array is defined as empty), the expand/collapse icons still render. I believe that if the length of the nodes array is zero, this should be treated the same as not supplying a nodes property.

My current workaround is for my TreeNode typescript class to provide a trimNodes() function:

      public trimNodes() {

            if (this.nodes.length == 0) {
                delete (this as any).nodes;
            } else {
                for (const node of this.nodes) {
                    node.trimNodes();
                }
            }

        }

While this works, and is easy enough, it would be nice if bstreeview handled this internally.
