Url received in node was decoded

[iskiselev]

When request is transferred from IIS to Node, it is decoded.
I do request to http://.../%24%3A%2Fcore%2Ftemplates%2Ftiddlywiki5.js.

I got next application output when it is executed on node natively:

Request path: {"protocol":null,"slashes":null,"auth":null,"host":null,"port":null,"hostname":null,"hash":null,"search":null,"query":null,"pathname":"/$:/core/templates/tiddlywiki5.js","path":"/$:/core/templates/tiddlywiki5.js","href":"/$:/core/templates/tiddlywiki5.js"}

When I run similar in Azure App Service with IISNode I got next output:

So, instead of original request, I got request to: /$:/core/templates/tiddlywiki5.js

Issue is duplicate of tjanczuk#217. PR that should solve it (tjanczuk#486) still not merged.
Workaround suggested in tjanczuk#217 (comment) works perfectly.
