Steps to reproduce:
- open Discuss app with "General" as active thread
- open call settings in the inspector
- open a mailbox as active thread
Crash:
```
Cannot read showOnlyVideo of undefined
```
This happens because discuss has a single thread view
that is shared for any selected thread. However, the
call settings menu only makes sense for thread that
have call feature, which applies for only channels.
Mailboxes should not have any call settings menu.
