Does two things:
1. Revert "Revert "Add unique constraint to email branding domain""
This reverts commit af9cb30ef3.
2. Don’t allow empty string in email branding domain
Columns with multiple `null`s can have a uniqueness constraint. Columns
with multiple empty string values are not considered unique.
This commit:
- removes any duplicate empty string values
- casts empty strings to null string any time these columns are updated
---
Squashed into this single commits because these two things are not
atomic as individual commits.
Brandings with a domain set should be considered canonical. It doesn’t
make sense to have the same domain set on multiple different email
brands – you can’t tell which one to use.
‘GOV.UK’ doesn’t make sense as a type of brand. It only made sense as
a type of branding that a service had.
Since we’ve:
- deprecated the service branding column
- made sure it’s not used as a value in the email branding table
we can remove this value from the table of possible brand types.
We’ve already removed all the `null` values, and made it impossible to
add new brandings with a `null` brand type.
Making it a database constraint just gives us extra safety.
So later we can:
- make it non-nullable later
- remove `govuk` as an option
This is mostly for people’s local databases, the manual work here has
been done on production already.

We are now setting the type of branding on the branding itself, not on
the service.
This commit switches over from looking in the old place (on the service)
to looking in the new place (on the branding).
Notify antivirus, on success, calls the process_virus_scan_passed taks.
Previously, this task would:
* update status to created (or delivered for test keys)
* copy the file from the scan bucket to either the live or test bucket
based on the results
* delete the old file in the scan bucket
We want it to:
* download file from scan bucket
* sanitise PDF using new template-preview functionality
* if sanitise failed, set to new status "validation-failed" and save
the pdf somewhere.
* send new pdf to live/test bucket
* update status to created (or delivered for test keys)
* delete the original file in the scan bucket
This PR does some of that:
* download file from scan bucket
* sanitise PDF using new template-preview functionality
* if sanitise failed, just log.
* send OLD pdf to live/test bucket
* update status to created (or delivered for test keys)
* delete the original file in the scan bucket
So if sanitising fails, we won't fall over and not deliver the letter,
we'll just log a message for now. If sanitise throws an unexpected
error (as opposed to a 400), we'll retry up to fifteen times (the same
as when creating a new letter). I've added the code for using the
sanitised pdf, but it's commented out for now
