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.
Thanks to David Cok for inquiring about this.
