Elasticsearch - display link to related view for artefacts in search results

[Robert Lyon]

Now that we use the 'doc' type in Elasticsearch 5+/6+ we need to adjust the views_by_artefact_acl_filter() so that it finds/returns the view(s) related to the artefact being displayed in the results

Bug 1740208: Fetch related view for artefacts we can see

Fix the way we find the related views now that we don't have a 'view'
type to restrict to. We can achieve this via the internal '_id' value
as that is a combination of old type and id values.

Also strip tags except the <span> one from highlighted description code
in case there is bad html/js in there.
