Subject: [PATCH 1/4] generator: Passing "" to StringList tests should turn into empty list.

This is a bug in the generator which wasn't being tickled.  If
you had a test which expected a StringList or DeviceList parameter,
and you passed "" to that test, then you'd (probably) expect to be
testing an empty list, but in fact you got a single element list
containing an empty string.  This fixes it so you get an empty list.
