fix crash in order writing in pkgDPkgPM::WriteApportReport()

libapt can be configured to write various bits of information to a file
creating a report via apport. This is disabled by default in Debian and
apport residing only in /experimental so far, but Ubuntu and other
derivatives have this (in some versions) enabled by default and there is
no regression potentially here.

The crash is caused by a mismatch of operations vs. strings for
operations, so adding the missing strings for these operations solves
the problem.
