Resolves: tdf#100838 no transparency support on using original jpg data path
This became a problem since...
commit 76ec54e8c9f3580450bca85236a4f5af0c328588

tdf#97662 - Try to preserve original compressed JPEGs harder.
Avoiding de-compressing and re-compressing them saves lots of time too.
for the default JPEG Compress + Reduce Image resolution case
but appears to always be a problem with the Lossless - Reduce Image resolution
case.
