Settings search used to work only on properties, so if a searchbox text
was a substring of a category but not of a property the whole category
would be filtered out and no property would be shown.
Now the behaviour is changed so that when the searchbox text is a
substring of a category all its properties are shown too.
The previous behaviour is still present so that in case the searchbox
text is both a substring of a category and a property of another
category, all properties of the first category are shown and only the
property of the second category is shown.
