[ClangImporter] Follow swift_name more closely when error params are involved.

  + (Foo *)foo:(id)obj error:(NSError **)error NS_SWIFT_NAME(init(object:));
  + (Foo *)foo:(id)obj error:(NSError **)error NS_SWIFT_NAME(init(object:error:));

These are now mapped, respectively, to

  init(object: AnyObject) throws
  init(object: AnyObject, error: ()) throws

rather than both mapping to the first one and having no way to specify the second.
