Avoid returning a version of "None"

If we don't detect even a potential version, we want to raise an
exception rather than returning None.
Avoid raising a KeyError when checking 'appName'.

We want to default to not doing the GeoIP lookup, but we don't
want the entire conversion to fail. Avoid a KeyError if the
'info' section doesn't have 'appName'.
Ensure that ANR payloads don't do GeoIP lookups.
