Cascading WMS stores do not play well with Geoserver Explorer

[gioman]

Tried to make a GET request to http://x.x.x.x/geoserver/rest/workspaces/cite/wmsstores/azz_azz/wmslayers/Bacias_hidrográficas.xml but got a 404 status code: No such cascaded wms layer: cite,azz_azz,Bacias_hidrogr%C3%A1ficas

if the store has spaces in it a different error is thrown (where the spaces seems to be not a problem anymore for other type of stores)
