Prior to this patch, the following returned an immutable vector:
(define empty-model (solve (void)))
(evaluate (vector-immutable 1) empty-model)
However, the following returned a _mutable_ vector, even though
`evaluate` is given an immutable vector (containing no symbolics):
(define-symbolic* b boolean?)
(define model (solve (assert b)))
(evaluate (vector-immutable 1) model)
With this patch, both examples above return an immutable vector.
