John Blackbourn 6a33072f68 General: Ignore invalid types for the '_wp_http_referer' URL query variable. ...

It's expected that this query variable contains a string when it's set, but it's possible for its type to be something else such as an array. Ignoring non-string values prevents cascading errors when its value is passed through functions that expect a string.
