3b546b2348 smt_context: we can't assert that the resource limits were exceeded on cancel_exception 
It happens sometimes that e.g. the internalizer goes above the soft memory limit
But since it's only by a small amount, when the exception propagates back to the context, some stuff
has been freed already and we are not longer above the memory threshold
Just delete these asserts

5d33805c8b optimize ~relevancy_propagator_imp() so it just dec refs the exprs in the trail 
It avoid doing all the funky watch stuff
One extreme Alive2 test case goes from 40s to 28s :)
