Test error: Modal being returned by getByLabelText queries when it shouldn't

[wise-king-sullyman]

Please describe the issue
In Koku we're seeing Modal being returned by getByLabelText queries when it isn't labelled with the query term and wasn't returned with the old label. Specifically it appears that when a modal has an aria-label it's setting the aria-labelledby automatically in a way that is self referential and causes it to turn up in queries that it shouldn't.
