Inside depgraph.loadResumeCommand(), ignore unsatisified dependencies that
are pulled in by installed packages. This is needed in order to avoid having
--keep-going bail out needlessly when one of a group of circularly dependent
packages fails to install after one or more of the group have already been
installed. TODO: Add sanity checks to make sure that it's really safe to
ignore all the deps that can be ignored by this code. (trunk r12541)
