When parsing the main query, if `s` is set to empty: `?s=` and `$this->is_main_query() && array_key_exists( 's', $this->query )` - kill the query instead of loading the homepage. This will load the search page with no results.

If `post__in` or `post_parent__in` is passed to `WP_Query` as an empty array, nuke the query. Both vars are currently only checked for truthiness after which they are ignored. Setting these vars at all indicates explicit filtering being desired.

When queries are passed to `WP_Tax_Query`, the value for `operator` is assumed to be uppercase. This is an unnecessary constraint. In `->get_sql()`, cast it using `$operator = strtoupper( $query['operator'] )`.
