Ben Langmuir 8f38e4b765 [code-completion] Avoid invalid member substitution for keypath dynamic lookup ...

When performing keypath dynamic member lookup, avoid substituting the
base type in override detection and completion, as the base type of the
lookup is not the base type of the member. For now, we just avoid the
substitution entirely to fix potential crashes; in a future commit we
will change to using the subscript return type and substituting with the
base type of the subscript instead of the base type of the lookup.
