normalize request path takes into account localhost

[napicella]

When using sam local the host is set to localhost.
In this case the path does not need to be normalized.

Details

Without this change, the router removes the first part of the url path, i.e.

> curl -H 'Content-Type: application/json; Host: http://whatever' -X PUT -d '{"message" : "hello" }' http://localhost:3000/a/b/c
{"message":"Could not find matching action for /b/c and method PUT","error":"NO_MATCHING_ACTION"}

Basically /a was removed from the path.

The fix

Check if the Host is localhost. In this case, just skip normalization.

Sorry for getting back to you so late to you. I know it's only a small change but could you add a test please? Thank you
