Message:

Code Modernization: Return false from wpdb::query() if the query was filtered to an empty string using the query filter.

This avoids a fatal error on PHP 8 caused by passing an empty string to mysqli_query(), and maintains the current behaviour.

Follow-up to [48980], [48981].

See #50913, #50639.
