Example scenario:

Given I am user A
Given I receive a call
When I make a direct transfer via my phone to user B
When user B fallbacks the call to switchboard C (via fallbacks, not forwards)
Then switchboard C events are not sent on the websocket

Expected: events for switchboard C are sent on the websocket

Technical details: the WAZO_TENANT_UUID variable is not always set on internal dialplan calls, especially on transfers made from a phone
