Nikolaj Bjorner 09696e989e add missing lambda defs per #5509 
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).

can't use auto-config if there are no assertions. Auto-config only works properly for one-shot mode since theories aren't loaded on demand in this solver.

@wintersteiger: added code review comment to theory_fpa. The bug seen in #5454 doesn't surface with theory_fpa, though.

Nikolaj Bjorner c959e28d4a remove prints, remove ability to toggle eager_eq_axioms option 
NB. Spacer sets eager_eq_axioms option to false, but relevancy of this option is not clear at all as all other default paths don't use this option and theory_lra is incorrect when it is set to false.
