Fix for #1307 (Oauth login not working)

- Changed blueprint reference in Backend from name to id, users can now again be found
- Depending on version of flask-dance the resultcode of authorized is set different to prevent redirect loop with newer versions(>1.3)
- Redirect to login page in case no user is linked to current oauth account
- Flash messages upon successfull login, successsfull linked account
