Fix convert-to-NIA stillImage check

For example, this GIF image:
https://github.com/google/wuffs/blob/e44920d/test/data/artificial-gif/pixel-data-too-much-bad-lzw.gif
which is 'disassembled' here:
https://github.com/google/wuffs/blob/e44920d/test/data/artificial-gif/pixel-data-too-much-bad-lzw.gif.make-artificial.txt
only has one frame, regardless of how the GIF codec implementation deals
with the LZW-compression error. It is not an animated image.
Nonetheless, frameInfos.size() returns 1, not 0, so prior to this
commit, "stillImage = frameInfos.empty()" assigned false, not true.
