tests: the self-revoke routing check reads the URL map; its 400 moves to Postgres

test_devices signed a fake account into a session and relied on
login_required answering without the database. Since 3dd0b44 the session
path reads the account's epoch, so the fake account hit an unreachable
database and 500ed. The routing property (the static /devices/self rule beats
/devices/<device_id>) is now asserted on the URL map, and the view's 400 for a
web session is an integration test with a real account. #5173.
