- The test_email job is removed, because it was always being run synchronously (not in sidekiq)
- 34b29f62 added a bypass for critical emails, to match the spec. This removes the bypass, and removes the spec.
- This adapts the specs for 72ffabf6, so that they check for emails being sent
- This reimplements c2797921, allowing test emails to be sent even when emails are disabled
This reverts commit c279792130e24dffbbdee8d6cbb0bad46cc13b72.
This commit inadvertently removed all of the non-staff email logic, rather than just for the 'test email' button.
