In search results, title should be title for laws

When searching for 'Lagar' the javascript created resultpage used
identifier as title for everything except 'Myndighetsforordningar'.

When looking upon searchResultByCategory.gsp which is loaded when the
search result page is reloaded it seems like title should not be
identifyer for 'Lagar' as well. Fixes #128
