is not reducible to a Pi. Example: if Not A = A -> False, Not A is not a

Fixed a bug in the unification, which prevented some reduction steps from being
performed in the case "match vs. match", when the types of the matching term
were not the same. The procedure used to always raise an Uncertain exception,
while in many cases the good choice would be to raise KeepReducing. This caused
the nnormalize tactic to fail with an error in some cases.
