Recette Bug - 6299

Context :

For the ticket 6299

When I have on my project project-nos-0.10.0 installed a wrapper, that links to glefevre-SANDBOX-3.7.0 via a wrapper 

Both Studio Projects are installed on my instance, however when I look at WEBUI, I get no elements appearing, and the following error in inspect 

Failed to load resource: the server responded with a status of 404 () 

/nuxeo-glefevre-SANDBOX-bundle.html

and 

nuxeo-project-nos-bundle.html

Note these elements are not appearing in nxserver/nuxeo.war/ui
