Switch text from National to Norwegian

friends.

Resolves: GREG-275

Fix bug in user info fetching on invite page

See merge request !342

By using onTouched mode validation does not complain about invalid
values until the users have changed focus from the field. Doing it this
way we don't complain about values until the user tries to use an
invalid one.

Does not work for all fields. For that to be the case, we will have to
do some clean up of controlled and uncontrolled values.

Fix problems with submit button not being disabled and some UX improvements
