Robert Widmann 9e496d38f9 Add a Null Check for Missing Generic Signatures

When an extension is nested inside of an invalid decl context, it is
going to pull the signature of its nearest enclosing context instead of
its extended type. This leads to a null signature since the nearest
enclosing context for an extension should always be its parent source
file.
