When an email fails, and you reschedule the post, the error dialog was
shown (from the previous try). The retry button on that page allowed you
to retry sending the email immediately, which could be very confusing.
- The email error dialog is no longer shown for scheduled emails
- The email status is no longer polled for scheduled emails
- Retrying an email is not possible via the API if the post status is
not published or sent
- Added some extra snapshot tests
- When retrying an email, we immediately update the email status to
'pending' to have a better API response (instead of still returning
failed).
- Disabled email sending retrying in development (otherwise very hard to
test failed emails if it takes 10 mins before it gives up automatic
retrying)

The email sending is a crucial flow that should not be interrupted. If
there are database connection issues, we should try to recover from them
automatically by retrying individual database queries and transactions
for a limited amount of time.
This adds a helper method to retry database operations. It limits all
database queries before sending the actual email to maximum 10 minutes.
Database operations that happen after sending have a higher retry time
because they are more crucial to prevent data loss (e.g. saving that an
email was sent).

This change adds a small sleep in between dispatching events in the
worker thread that reads the events from Mailgun. That should reduce the
amount of queries we fire parallel to each other and could cause the
connection pool to run out of connections.
It also reduces the amount of concurrent sending to 2 from 10. Also to
make sure the connection pool doesn't run out of connections while
sending emails, and to reduce the chance of new connections falling back
on a (delayed) replicated database.
no issue
Tests stopped working because the Mailgun mocker stopped working since we moved to the new email flow.
This also fixes a unit test that needed to get updated.
