Behdad Esfahbod f916971913 [instancer] Fix output filename decision-making
All limits are tuples now when not None. The old logic was
broken and for the following command:

$ fonttools varLib.instancer  AdobeVFPrototype.otf CNTR=50:80 wght=900

it was saving the output with the name suffix `-instance`, whereas
it's clearly a partial instantiation. This fixes that.
