Flush the query results variables following strip_invalid_text_from_query() to ensure queries from that function does not get returned to the caller function.

This changeset to wpdb was never added to to HyperDB.

18 months ago I merged it to our HyperDB on WordPress.org, but appear to have failed to create a PR here, and don't recall what I was fixing at the time. It appears it was likely causing PHP Notices somehow or causing problems in the WordPress.org stats.

Based on the core bug it was fixing, it appears it may also affect some unit tets.

@pento I don't suppose you recall any details of the above changeset, and if/why/not it should be added to HyperDB too?
