First uploader should be credited, not last.

Currently it looks like whover uploaded the latest version gets credited as the Photographer. E.g. for Valö2, Vrångöskärgård.jpg We see that Embedded_Data_Bot is credited instead of Yvalima.

As this also affects participant and new user counts it can potentially skew the statistics.

@JeanFred Unsure if issues are tracked here or somewhere on Phabricator (now that code lives in gerrit)
