07a1aea689 fix(spacer): bug in assign_bounds to Farkas conversion 
The fix is to remove a hack that used a theory rewriter to simplify
the conversion. Now the conversion happens less often than possible.
Will need more thinking to fix properly.

The unsoundness at this point would cause SPACER to generate lemmas
that do not block a proof obligation and then get stuck in an infinite loop
blocking and generating the same lemma.
