Remove unreachable code

[cnlucas]

What we’re after

When @tmpayton built our new legal tests, she found a few sections of dead code that should be removed.

in legal.py we should remove lines 492-495:

if kwargs.get("case_dispositions"):
        must_clauses.append(
            Q("term", disposition__data__disposition=kwargs.get("case_dispositions"))
        )

and lines 118-121

# if doc_types is not in one of ALL_DOCUMENT_TYPES
            # then reset type = all (= ALL_DOCUMENT_TYPES)
            if doc_types[0] not in ALL_DOCUMENT_TYPES:
                doc_types = ALL_DOCUMENT_TYPES
