Incorrect French abbreviation in seeding, making French translation unusable.

[Sean-Stilwell]

What version of the DMPRoadmap code are you running? (e.g. v2.2.0) v3.1.1

Expected behaviour: French translated version opens when changing language in the language toggle.

Actual behaviour: Reverts to the default (en-GB for me) version. This does not occur with the Spanish, German, Turkish, or Portuguese translations (i.e it's exclusive to French).

Cause: In db/seeds.rb, the following is a value from the languages array:

{abbreviation: 'fr',
   description: '',
   name: 'Français',
   default_language: false},

The 'fr' abbreviation should be replaced by either 'fr-FR' or 'fr-CA'. Manually updating this value in my database to either abbreviation corrected this issue for me.
