fix(typesense): do not try to sort by position when searching in a saved filter

This change fixes a bug where Typesense would try to sort by the project view of a saved filter. The view position is not indexed in Typesense, hence filtering fails. Because sorting by position is not a feature in saved filters, I've removed the logic for sorting saved filters with Typesense.
