Quote macro parsing bug

[maciektr]

Repro:

pub fn process(db: &SimpleParserDatabase, struct_ast: &ast::ItemStruct) -> TokenStream {

    let name_string = struct_ast.name(db).text(db).to_string();
    let name_token = TokenTree::Ident(Token::new(name_string.clone(), TextSpan::call_site()));

    let impl_string = format!("{}NameImpl", name_string.clone());
    let impl_token = TokenTree::Ident(Token::new(impl_string, TextSpan::call_site()));

    let res_string = format!("\"{}\"", name_string);
    let res_token = TokenTree::Ident(Token::new(res_string, TextSpan::call_site()));

    quote! {
        impl #impl_token of NameTrait<#name_token> {
            fn name(self: @#name_token) -> ByteArray {
                #res_token
            } 
        }
    }
}

generates:

 impl MyStructNameImplof NameTrait<MyStruct> {
