RequestInterface shows invalid URI

I'm, always getting the `"Not found"` error on my api calls. Tried investigating and found this on the $request passed to the `RequestInterface::sendRequest()` method:

```
Request {#346 ▼
-method: "GET"
-requestTarget: null
-uri: Uri {#347 ▼
-scheme: ""
-userInfo: ""
-host: ""
-port: null
-path: "/user/repos"
-query: "type=owner&sort=full_name&direction=asc"
-fragment: ""
}
-headers: []
-headerNames: []
-protocol: "1.1"
-stream: null
}
```

Seems like the `path` parameter is missing some parameters even though $`github->currentUser()->show()` shows a complete response:

```

"login" => "myusername"
"id" => xxxxxxxxx
"avatar_url" => "https://avatars2.githubusercontent.com/u/xxxxxxxxx?v=3"
"gravatar_id" => ""

"html_url" => "https://github.com/myusername"

```

Start at RequestInterface::sendRequest() and inspect how the Request and Uri values shown in the report are assembled for the user-repositories call. Reproduce the API request and compare the resulting URI with the endpoint represented by the current-user response; done means the request no longer produces the reported "Not found" error.
