ID lookups should warn or override when they conflict with `match.require` settings

I have a handfull of albums that Beets fails to recognize, yet that seem to be available in teh MusicBrainz database. That alone isn't the point of this report. Instead, even when I manually specify the MusicBrianz release ID for these albums, Beets stills comes back with an error:

`No matching release found for N tracks.`

I've pasted soem of the ID's in question below, along with links to teh MusicBrainz page and a listing of the corresponding directory.

For reference, my beets config and version are:

```
$ beet --version
beets version 1.3.10
plugins: info, fetchart, copyartifacts, inline, replaygain, duplicates, lastgenre, embedart, importadded, scrub, mbsync, lyrics, chroma, missing
```

Thoughts?

Reproduce the examples with `beet import`, especially ID entry for the two MusicBrainz releases, and inspect how the configured `match.require` settings affect that path. Done means an explicit, tested behavior when a supplied release ID conflicts with those requirements, either warning the user or allowing an override.
