Like in r16346, do not filter local definitions (here in the
type-based second-order unification algorithm).
In type-based second-order unification algorithm, protect local
definitions in instances of evars to wrongly be considered as
potentially flexible.
Altogether, this fixes the anomaly in #3003 (even if some additional
work has to be done to improve the resulting error message, see next
commit).
