Title: extra_data.update() was raising a TypeError because the field is created blank and is considered null by the JSONField

Prepopulates UserSocialAuth instance with an empty dictionary to allow the calling of extra_data.update() without raising a TypeError because the field was considered None when null.

I'm not sure if this is the best approach, but it's working now.
