The suggestion list under the place search showed the index's raw ISO code
("福岡市博多区, JP") and listed a place twice when the index and its
OpenStreetMap layer both carried it, which the search list after Enter
already merges. Suggestions now name the country through Intl in the
language of the search, and a layer row at the spot of an index row with a
matching name is dropped by the same rule mergeSearchResults uses, now
shared as samePlace.
