Revert some of #4226

Rectify a couple of things in that PR, pointed out here:
https://github.com/beetbox/beets/pull/4226#issuecomment-1011499620

- Undo the `pretend` sensitivity in the import path, because it's not
  clear how this setting could ever be true.
- Preserve the log message in debug mode, even when quiet.
