Fix PaypalIPN single function to not receive-by-reference

Overview

Fix PaypalIPN single function to not receive-by-reference

Before

public function single(&$input, &$ids, &$objects, $recur = FALSE, $first = FALSE) {

After

public function single($input, $ids, $objects, $recur = FALSE, $first = FALSE) {

Technical Details

The function is called from 2 places

• main
• recur

In both cases it is at the end of the function & so the vars, if altered, are not used again.
In the case of main they are internal to the function whereas for recur they are not returned to the
calling function (does not receive by reference)
