Adding amenity=funeral_hall from search menu removes building=funeral_hall

[Oivo35]

Adding amenity=funeral_hall from search menu removes tag building=funeral_hall.

1. original tag
   
2. choosing amenity=funeral_hall from menu
   
3. tags after adding amenity=funeral_hall

@Oivo35 could you please review #1324 (comment) if that fixes the issue and add some test cases to that PR? That would help a lot.

@tordans Thanks, now it seems fixed,
