This fixes the failure of the requiredby004 pactest in a not so pretty way, but it gets the job done. I purposely used the extremely long name of PM_TRANS_TYPE_REMOVEUPGRADE to be both clear and in the hope that someone else will figure out a better solution. Original idea from Nagy Gabor, patch updated and cleaned for current code. Signed-off-by: Dan McGee <dan@archlinux.org>
