The changes for general search suggestions added to this PR by mistake were reset.
The old person search tab is still alive.
The new persons search is provided with its own directive (that works with all 3 types of filters) so it doesn't affect the old version of search.

when switching between collection tabs url parameters relevant to persons search have to disappear
Toggling 'show less/more fields' must toggle values inside 'Place of Birth / Marriage / Death' and 'Place of Birth' input fields (if one of these fields is filled)
