fix presence channel

[nenads]

Hi love what have you done so far.

There is issue with presence channel:

1. Auth route returns extra data:

   {"auth":"2edb16a0a48b7cb9","channel_data":"{\"user_id\":1,\"user_info\":{\"id\":1,\"name\":\"admin\"}}"}

   Channel data needs to be send over Web-Socket to correspond with auth token for that channel.

2. Backed was json encoding string so auth would fail, since request parameter was never converted to array in first place.
