PERF: ensure sidebar section link index is correctly ordered (#20854)

Browse Source 
We perform lookups on sidebar section links based on sidebar_section_id
totally ignoring user. This ensures we have an index to work with.

This removes the previous index `links_user_id_section_id_position` which
partially doubled up `idx_unique_sidebar_section_links`
