tahoewapi demo tree-view.html always recurses to ro_uri in children.

[nejucomo]

The tahoewapi demo app called ./poc/tree-view.{html,js} always recurses using the ro_uri capability.

This means even if you enter a writecap on the make-tree-view.html page, then only the root node will have a "RW" link to the WUI.

Reproduction:

1. Go to ​the latest trunk demo page on testgrid.

2. Paste a writecap and make a tree view.

3. Attempt to browse to a descendent write cap WUI page via a tree view "RW" link.

Notes:

Once fixed in trunk, the link above will not reproduce the bug. However you can replace "/trunk" with "/releases/0" in the URL to reproduce the bug in the initial release. This "stable release" will never change.
