Fix c2.ignored.03 test actions

[naglis]

In my understanding, this test should produce a TOC with a single entry to Part 1, as shown in the test HTML document:

publ-tests/publication_manifest/toc_processing/tests/c2.ignored.03.html

Lines 76 to 90 in 4f8bd4c

	<section id="result">
	<h2>Result</h2>
	<p>Result of this test should be a structure like the following:</p>
	<pre>{
	"name": "Contents",
	"entries": [
	{
	"name": "Part 1",
	"url": "#p1",
	"type": null,
	"rel": null,
	"entries": null
	}
	]
	}</pre>
