Subject: [inc/Trigger] Fix Trigger::ipxe() when called multiple times

If during one execution we end up in Trigger::ipxe multiple
times, we wouldn't execute any hooks because of include_once.
This should be OK however, so instead of changing it to include,
just remember the $taskId and return it later.
