Summary XML doesn't contain information about input/output files

When processing the data from #495 (closed) in LHCbDIRAC the XML summary file (enabled by setting xml_summary_file = "summaryMoore_00012345_00006789_1.xml") that is created looks like:

<?xml version="1.0" encoding="UTF-8"?>

<summary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" xsi:noNamespaceSchemaLocation="$XMLSUMMARYBASEROOT/xml/XMLSummary.xsd">
	<success>True</success>
	<step>finalize</step>
	<usage>
		<stat useOf="MemoryMaximum" unit="KB">13178524.0</stat>
	</usage>
	<input />
	<output />
	<counters>
		<counter name="FutureNeutralProtoPAlg.CaloFutureHypoEstimator/no cluster">4316</counter>
		<counter name="CounterSummarySvc/handled">0</counter>
	</counters>
	<lumiCounters />
</summary>

This then results in LHCbDIRAC marking the job as failed as the input and output sections are empty. For reference LHCbDIRAC expects the file to look like:

summaryMoore_00162484_00027328_4.xml
