Date format in gnome-calendar does not match system locale

[Sam Braithwaite]

On a clean install of UbuntuGNOME 16.04.1 LTS x64, after the system locale has been set as en-GB during the installation, the date format in the GNOME calendar is displayed as "January 22 2017" instead of the correct date format for the locale, "22 January 2017". The correct date format is displayed when running the "date" command from the terminal, and the correct date format is displayed on the GNOME lock screen.
