hypothesis_reducer: worked around propositional literals
...
propositional formulas (disjunctions) can appear as literals. This
makes it tricky to recognize whether a formula is a unit clause when
re-building unit resolution.
Added work-around that identifies whether a formula is a literal based
on its appearance in previous unit resolution step.
