revive's unused-parameter rule flagged 7 test handler/method args:
- provider_test.go: fakeProvider.Configure(s) and
fakeAlbumProvider.FetchAlbumCover(ctx, mbid) — interface
conformance dummies that don't use their args.
- provider_mbcaa_test.go: 4 httptest handlers that ignore one or
both of (w, r).
- provider_theaudiodb_test.go: the disabled-provider negative
test's httptest handler.
All 7 renamed to _ per revive's convention.
