Improve the tests.

When a sponsor creates a new guest invitation, and when a guest corrects their name
they must now use transcribed characters.

- User prefetch_related to load data ahead of time
- Adds a new simple serializer, that does not use properties that
  triggers new queries

The old version of the client did not fetch short name correctly from
the api response. This new one does, but shortname is now called
short_name, forcing some small adjustments of the tests and their
settings.

Add comments field for roles
Removed contact_person_unit from read_only_fields for roles

Calling norwegian fnr "National ID number" makes people input their id
numbers from their home country in addition to their passport numbers.

This text change hopefully makes it clearer for our non-norwegian
friends.

Refactered the mail sending

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

Add a possibility to search via v1-api, and add birth date to the data in such a case. No changes for previous gui-endpoint.

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.

Was removed by mistake at some time in the past. Introduced a few tests
to ensure that things work as expected.
