## Description of the pull request
Running latest GetStream SDK (from version 2.0.0) calling `channel.markAllRead()` will throw an error similar to this:
```bash
I/flutter (10572): ----------------FIREBASE CRASHLYTICS----------------
I/flutter (10572): StreamChatNetworkError(code: -1, message: SocketException: Failed host lookup: 'chat-us-east-1.stream-io-api.comchannels' (OS Error: No address associated with hostname, errno = 7))
I/flutter (10572): #0 StreamHttpClient.post (package:stream_chat/src/core/http/stream_http_client.dart:158:7)

```
Adding a `/` to the front of the called URL will resolve this - I've done this locally and it works.
