8b572ade81 Found edge cases with custom qtables
And there was a lingering bug since the previous qtable unsigned char fix
(#1814) since the call to array.array was in another place, the roundtrip was no
longer equivalent.

That was a minor change, but the revised test wouldn't pass because saving an image
with one custom qtable automatically adds a second to it by the call to
jpeg_set_defaults.
With 1 or >2 custom tables, there is extra work we have to do due to that call.
