Discrepancy between imports from PBF and from overpass

[theja]

There seems to be a slight discrepancy in the number of destinations being imported between importing from a PBF file and overpass directly. It does not seem to be limited to multiple queries. In general, the overpass import rows seem to be slightly less in number than PBF imports. The number is pretty small and may not affect BNA results much, but something to look into for later. I suspect it has something to do with PBF potentially having historic locations as well as current ones. This is only a guess based on spot checking and will need to be explored more to be certain.
