Slava Pestov 5bb40ae66e Sema: Fix doesMemberHaveUnfulfillableConstraintsWithExistentialBase() for generic context ...

We don't want to pass in the outer generic signature here.

The base type's constraint type is written in terms of archetypes,
and we run generic signature queries against it with types appearing
in the protocol member. Since the protocol member has Self at
depth 0, index 0, prepending the outer generic signature to the
opened existential signature would produce incorrect results.
