fix: respect query and required parameters

[tshedor]

The router doesn't include optional query-string parameters when required parameters are present.

For example, /route/:id and /route?id=1 are respected, but /route/:id/profile?title=dev only parses :id. This PR provides :id and title to Get.parameters
