attempt to find resource by listing

add a last-ditch effort to find the resource in question by
listing all the resources and doing a simply match for name and
id. if no match is found then raise an error, if the list call
is unsuccessful, raise the same error. we have failed this city.

Closes-Bug: #1501362
