datacite: improve date handling and minor tweak

Records from https://www.micropublication.org/ did not have a date in
FC, although raw data contained date strings - they were not using the
finer-grained "attributes.date" but "attributes.published" and/or
"attributes.publicationYear".

Support for those fields has been added, including a test case.

During this test (#30) a processing gap for names became clear (author
may have "given_name" and "surname", but no "name"). This bug has been
fixed, too.
