At the moment we’re not consistent:
Precompiled (API and one-off):
`to` has the whole address
`normalised_to` has nothing
Templated (API, CSV and one off):
`to` has the first line of the address
`normalised_to` has nothing
This commit makes us consistently store the whole address in the `to`
field. We think that people might want to search by postcode, not just
first line of the address.
This commit also starts to populate the normalised_to field with the
address lowercased and with all spaces removed, to make it easier to
search on.
we now no longer create a job. At the end of the post there is no
action, as we don't have any tasks to queue immediately - if it's a
real notification it'll get picked up in the evening scheduled task.
If it's a test notification, we create it with an initial status of
sending so that we can be sure it'll never get picked up - and then we
trigger the update-letter-notifications-to-sent-to-dvla task to sent
the sent-at/by.
1. No longer create jobs when creating letters from api 🎉
2. Bulk update notifications based on the notification references after
we send them to DVLA - either as success or as error
so they can be distinguished on the frontend.
Also, some related cleanup:
* don't show test api letters on the frontpage
* make sure the subject is returned from the API for letters
* make sure the letter's address is returned for letters
there are three steps to this
1. Create a job
* Starts in status 'ready to send'
* Created by None, since it's from the API
* original file name 'letter submitted via api'
2. Create a single notification for that job
* job_row_number 0
* client reference if provided
* address line 1 as recipient
3. Trigger the build_dvla_file task
we know that all the notifications have been created for this job
(since we just created them ourselves synchronously), so this will
just create the dvla-format file for the job, and upload it to s3.
