Race condition when trying to authenticate private channels

[xAockd]

Step to reproduce:

1. simulate long running subscription response on app backend
2. restart centrifugo while the subscription is running

Response:
error in reply client=aaa32115-f0e6-4049-84f7-92f2a75ac4c3 command="id:55 method:SUBSCRIBE params:"{"channel":"$privte.channel","token":"token"}" " error="103: permission denied" reply="id:55 error:<code:103 message:"permission denied" > " user=3389

Additional technical details:
If long-running subscription only for the first request we receive another error

It fixed for me the issue.
Probably it's not the best option. But as a hotfix...
#77
