perf: make the tours archive query index-only by default

Browse Source 
The archive attached an always-on _vc_featured NOT EXISTS join and a
_vc_review_count join (plus SQL_CALC_FOUND_ROWS) to every request, which made
/tours/ crawl/time out over a ~70k-tour catalogue. Default sort now orders by
post date with no postmeta joins; price/rating sorts add a single meta_key join
on demand; meta_query is only attached when a filter is active. Bump 1.8.4.
