Failure to detect a proxy IP results in none

[shadowhand]

Our production infrastructure includes a load balancer, so we use$clientIp->proxy() to enable the original IP address of the user.

However, in development there is no LB so proxy IP detection fails. Due to this condition, if no IP is detected during the loop, then a void return is used.

The solution is simple, add this to the end of the method:

return $ip;
