Use a dummy ident for a lint_if_path_starts_with_module call.

Browse source 
This is pretty weird code. As the `HACK` comment indicates, we push the
empty ident here only to make the path longer, so certain checks to
occur within `lint_if_path_starts_with_module`. `dummy` is a better
choice because it explicitly communicates that the actual value doesn't
matter.
