Leave the node's own copy of a module's resource out, and carry the kept declaration's filled paths (issue 1945)

The node's own composition and a module's both declared the same files, and
the joined declaration was refused whole ("2 resources declare X"): the
node's own copy is now left out when joining and at the node's own apply, and
said once (1945/AC17). A module still running from the kept declaration now
carries its filled paths, so the filling no longer refuses them as not named
as filled (1945/AC18).
