Protect spacer from existential quantifiers in the tail.

Some transformations seem to introduce existentially quantified terms.

better proof generation for the case when the query is reachable from initial
states. This case needs to be handled better so that spacer can assume
the problem is non-trivial.

Arie Gurfinkel b1b77e57e1 (partial) fix #3788 
Fixes a bug in computation of implicants inside spacer.
The instance now returns `unknown`. The root cause is the difference in what
proofs are in spacer and SMT. Spacer returns a proof of query, but horn_tactic
expects a proof of FALSE.
