tools/tests: correct variant parsing
Seen in NM 1.42.6 where there is now a ipv4.dns-data key which have as signature: dbus.Array([dbus.String('a.b.c.d')], signature=dbus.Signature('s'), variant_level=1)
This lead to the following exception: Cannot convert array element to type 's': Must be string, not Variant
Moreover, the exception TypeError has no message field so it raised another expcetion which gave me trouble to find what's going on.
Hence the addition of a log file from the previous commit
