Don't allow get-model & co after a user push/pop
This makes us more strictly adhere to the spec, but it's useful anyway:
previously we would support a get-model until the problem was explicitly
changed with e.g. a new assertion. That meant you could check-sat, then
pop, then get-model, but you'd only get the part of the model still in
scope. This is strange, and would likely lead to problems, so it's now
disabled.
