fix(jobdanmark-search): drop a malformed closing tag the parser left as text (#526)

A live page wrote its Jobtype item as "Fuldtid </ li >". node-html-parser
consumes well-formed markup but does not recognise a closing tag with a
space after the "<" or the slash, so the fragment became a text node and
overviewValue kept it: employmentType: ["Fuldtid </ li >"], matching none
of the documented job-type vocabulary. The same cleanText feeds every
text field on both branches.

Strip only the closing-tag shape in cleanText before collapsing
whitespace. The parser decodes entities before cleanText runs, so author
text the page encoded as &lt;div&gt; or &lt;T&gt; arrives as a literal
<div> / <T> and must stay; a probe of what the parser leaks shows only
malformed closing shapes (</ li >, </ li>, < /li>). Two fixtures: the
stray tag in both the Jobtype item and a description paragraph (fails on
master), and an entity-encoded <div> that survives.

Observed by the maintainer in the #516 merge note.
