tests: Widen @covers annotations

> We lose useful coverage and spend valuable time keeping these tags
> accurate through refactors (or worse, forget to do so).
>
> I am not disabling the "only track coverage of specified subject"
> benefits, nor am I claiming coverage in in classes outside the
> subject under test.
>
> Tracking tiny per-method details wastes time in keeping tags
> in sync during refactors, and time to realize (and fix) when people
> inevitably don't keep them in sync, and time lost in finding
> uncovered code to write tests for only to realize it was already
> covered but "not yet claimed".
