433: fix(filter): Fix two bugs. r=Kerollmops a=irevoire

- Stop lowercasing the field when looking in the field id map
- When a field id does not exist it means there is currently zero
  documents containing this field thus we return an empty RoaringBitmap
  instead of throwing an internal error

Will fix https://github.com/meilisearch/MeiliSearch/issues/2082 once meilisearch is released
