Do not upgrade rev-deps ear-marked for removal
We schedule reverse dependencies for an upgrade, but we shouldn't do it
if we have ear-marked this package for removal later on. Usually the
solver will end up doing the right thing like it already did in the
included testcase in the end, but given that before it reaches the right
end it explored a bad path which can lead to more installs and removals
influencing later decisions or are just too hard for the resolver to
undo later on, we can just not explore this path to begin with.
