Comment (by costdev):

 Thanks @xknown!

 My understanding is that `_wp_http_referer`, like `HTTP_REFERER`, should
 always be a string. I haven't found any references to it being acceptable
 or used as an array.

 So if the issue is just that `wp_get_referer()` isn't enforcing its
 documented return types, then the PR looks good to me! - I just left a
 comment with a small change to the test method's name.
