feat(collection): remove unnecessary `OptionalWrapper` 

- In a label collection, there is no need for a `None` label. One should
  just not add that label
- Code wise it is also incorrect. The wrapper will be for a vector of
  spans, not for individual spans. It happens to work anyway, but this was
  not the intended use.
