feat: remove unnecessary filter creations

[Cali0707]

The filters field is implicitly an AllFilter, which means that even if a user only creates a single filter two filters will get created. Similarly, if for some reason a user creates an all filter or any filter with only a single subfilter, we should not create the extra "wrapper" filter.

Proposed Changes

• Only create an all or any filter if the filters list is > 1

@Cali0707 can you rebase this? It seems I can't push to your branch to rebase on my own :/
