Oh, and a transaction block. Because the controller after hooks tried to update the DB which resulted in
PG::InFailedSqlTransaction: ERROR: current transaction is aborted, commands ignored until end of transaction block
Even for a small rescue statement, it's worth adding a spec. You never know what might not be working!
* Clarify that it's a request spec, not testing a controller directly.
* Use `before` block to avoid side effects changing config at load time.
* Better name the test action as request instead of plain "subject".
* Move assignments into `before` block instead of variable.
