outputGenerator tweaks

[missinglink]

In the following example, the 'text' should be 'Arbil, Iraq' but due to the way the outputGenerator is written it matches nothing for local and 'Arbil' for regional (the name is also 'Arbil').

If I simply add admin1 to the end of the local array then both local and regional will match 'Arbil' and when the de-duper removes one entry, we are back with the text being 'Arbil'.

Not sure if I described this well, but basically we need to continue checking values in the local and regional arrays until we find a value which is not a duplicate of the name or another admin value, otherwise a POI with { "name": "a", "local_admin": "a", "admin1_abbr": "a", "admin0": "b" } will always just be a when it would be nicer if it were a, b.

Hope that makes sense ;)
