fix: encode ws url (#3498)

Summary:
Some clients require encoded ws url. For example on Android (running in Rect Native), plain URL like this:
`ws://10.0.2.2:8333?device_id=ReactNative1646120067758.0.2246373385349361&device=ReactNative&app=React Native App Google - Android SDK&os=ReactNative`
will throw error during connection.

To not require param encoding when starting the `flipperClient.start()`, it is easier to encode entire `url` before starting the ws server.

## Changelog
