Overview

Fix bug where getsingle calls chained actions twice

Before

When calling

$contribution = $this->callAPISuccess('contribution', 'getsingle', array(
      'id' => $contribution['id'],
      'api.contribution.delete' => 1,
    ));

the delete is called twice

After

$contribution = $this->callAPISuccess('contribution', 'getsingle', array(
      'id' => $contribution['id'],
      'api.contribution.delete' => 1,
    ));

the delete is called once

Technical Details

A bit hacky but I don't want to go too far down this rabbit hole & I did manage to get in a test

This is a bit hacky but it is limited to getsingle actions and it has a test which has passed. On balance i think this is better in rather than out. Merging
