Nikolaj Bjorner 5a479fca76 generalize model finder code to be independent of conjunction elimination

Nikolaj Bjorner 357b4b20fd fix #1365. Filter MBQI instantiations for as-array terms that lead the array theory to return unknown and therefore block further instantiations. as-array terms are at this point almost always created from internal model values so quantifier instantiations with these have little value, other than instantiations of other paraameters that may indepdendently help
