solver3: Actually restore unsolved items rather than solved ones
When restoring previously solved items, we try to restore items
that have become unsolved again by skipping items that have a
solved solution.
Well at least we thought we did, but we accidentally had a "not"
in there that inverted the meaning, hence we lost work items on
backtracking.
This mostly did not seem to have caused any issues, I stumbled
over it while trying to add `autoremove` listings to `upgrade`,
but fixing it also fixes:
test-ubuntu-bug-1130419-prefer-installed-ma-same-siblings
This used to say "E: Broken packages", meaning the solver lost
a non-optional install request and the 2nd stage solver caught
an incomplete solution.
Also test-bug-735967-lib32-to-i386-unavailable restores the legacy
solver behavior, so win win?
