We're making unnecessary edits when a statement hasn't changed but we're updating the data to include a new retrieved from EuPMC date (today).

See: https://www.wikidata.org/w/index.php?title=Q30252774&diff=prev&oldid=503799022

We should see how close the date is and not bump if under, say, 60 days.
