I think that these assertions are unique to this test. They look a little like [the tests for newly-created Alarm list items](https://github.com/mozilla-b2g/gaia/pull/12594/files#diff-92a9c028050b18d203ce21f26e7737f3R68), but they are actually guaranteeing that the "Alarm edit" form is pre-populated to reflect the state of the alarm.
