* fix(SW-1177): fix localization problems in search history
When saving search history the whole location objects where stored and
also used later. This made the list display in different languages if
the user previously had search for something in another language.
Another issue where that the list where also deduped based on name of
the search item, which meant that there could be multiple history
items for the same entity and the same ID, e.g. `Gothenburg` and
`Göteborg`.
