Test fails on Windows in router_test.go

[as27]

When running go test on a windows machine, the test fails in router_test.go

--- FAIL: Test_Resource (0.00s)
Error Trace: router_test.go:198
Error: Received unexpected error "parse http://127.0.0.1:50094\\users: invalid character "\\" in host name"

Looking inside the test shows, that the bug is inside the test. A url is joined using filepath.Join() That may work on linux or mac, but not on windows:

	for _, path := range []string{"/users", "/api/v1/users"} {
		for _, test := range tests {
			u := ts.URL + filepath.Join(path, test.Path)
			req, err := http.NewRequest(test.Method, u, nil)

After correcting the path, there are still bugs inside the test cases. Everywhere "/" is called gives then a 404. That is because the filepath.Join() did not add a backslash in that case.
If the path is "/" like here:

{
	Method: "GET",
	Path:   "/",
	Result: "list",
}

The path needs to be "". So also the testcases are not correct at that part.
