Fixed Dynamic Parameters in routes containing spaces

[aldrino]

The change here is to appropriately fetch the baseUrl in cases where the URL is encoded.

• req.originalUrl - http://localhost:3000/blog/how-to-use%20sapper
• req.url - http://localhost:3000/blog/how-to-use sapper

Current req.baseUrl - http://localhost:3000/b/ (Fails loading of assets) Expected req.baseUrl - http://localhost:3000/

This would need a test. I'm a bit hesitant to merge anything else into Sapper though. Is there any reason you don't just use SvelteKit?

SvelteKit 1.0 is now out and Sapper is deprecated, so I'm going to close this
