The Metadata/Preservation Service attempts to collect extra metadata about DOI references by resolving the DOIs. If there is a problem with the resolution (like the DOI does not exist), the service is supposed to just say "oh well" and move on. However, an undeclared in exception type (DOIResolutionException) in the "oh well" code block caused the service to fail. This PR corrects this problem to restore the service's "oh well" attitude.
