collada2gltf: fix URL problems

collada2gltf does not handle Windows pathes, the used COLLADABU::URI
class can't parse native Windows pathes so call COLLADA2GLTFWriter
with URL only.
Other problems:
collada2gltf uses the URL path for creating/opening files,
instead of native ones.
collada2gltf initializes _outputFilePath member in different way,
sometimes as an URL path, sometimes as a native one, but handle it
on the same way(as an URL).
