Search results don't display custom labels

Summary

There are two bugs that are related here:

1. While Admin UI can set both featureTitle and shortFeatureTitle, there is a bug in Client that will display the featureTitle not only in the search results list but also as a map label - where shortFeatureTitle was intended to be used.
2. Putting the value of featureTitle or shortFeatureTitle inside quotation marks doesn't do what's expected (it should display the value as-is, if string is surrounded by double quotes). (See FeatureInfo: Make it possible for admins to set a hard-coded label when no good attribute values exists on dataset #1126.)

Description

In #1126 I've added the possibility to define hard-coded labels that will be used in search results list and map view, as labels, in case of lacking values in the data source:

This does work as expected:

Gives:

Now, there's also a possibility to set a label that will be displayed in map:

This does not work as intended however. The MapClickViewer/FeatureInfo/Infoclick part is doing fine:

However, if this layer happens to be active as a search source too, we would expect the value of short display field "Landsbygd B" to show up. It doesn't:

I noticed that this introduced a new bug as the labels are visible in the early stage:

We want labels to show only in highlight mode, i.e. restore the functionality introduced in #1002.
