We no longer email sponsors(hosts) if they don't need to verify any of
the information provided by their guest.

Sponsosr can now click a button next to passport/fnr values on the
guest info page to see the source and verifier of the value.

Introduces the invalid field on the Identity model. The field is used to
indicate that the Identity is in invalid. This is useful when a value is
not a working value, even though the value passes validation checks,
like unused national id numbers, emails tied to non-existing domains,
etc.

If the sponsor writes a valid but non-existent email in a guest invite
we retried sending this email indefinitely. Instead of leaving django q
in an endless loop, we now send an email to the sponsor warning about
the problem instead.

Since we may not want to enable the identity check, it must be
togglable. This commit adds environment variable
REACT_APP_ENABLE_IGA_CHECK for toggling the check in the frontend, and
django settings variable IGA_CHECK for toggling the check in the
backend.

Move serializers only used by gregui.

Queries iga for an external id matching ours. If a match is found, the
name of the owner is returend. Otherwise we return null. Uses the new
iga module to fetch the data.

Verify that the backend accepts unicode for text fields and that it
survives to the database and back again

If a sponsor verifies a nin that is already in use by an account in
cerebrum, the guest will gain access to that account, which in turn
allows the guest to change the password of that account. This makes it
possible to abuse the guest service to steal the account of users.

A feature that checks for this problem, and helps the sponsor make a
decision on it, will be introduced in the near future. At that point
nin verification can be enabled again.

This ensures that identity values created from values written in the
frontend by guests are given a source value signifying so.

If the user logs in through the frontpage we now check if they have
completed the registration process. If they have completed it halfway
before, we find their info through the GregUserProfile of the user and
redirect to the register page. If we dont find any profile connected to
the user they are treated as anonymous users as before.
