Fix a JPEG2000 decoding regression

When neither the PDF nor the JPEG2000 image provides a colorspace, treat
images with 3 channels as though they are RGB and decode them, instead
of giving up and not decoding at all.

This fixes a regression from CL [1], and also reverts the change to
testing/resources/pixel/bug_304_expected.pdf.0.png from that CL.
Although Acrobat Reader rejects the image in the top-left quadrant and
renders it as white, most other PDF implementations will render is as
red.
