Bug 977056 - [Dialer] Visual discrepancies: Call ended view under conference call participants list

Anyhow, your proposal of directly inserting the call into the main call screen page if the group details are not displayed in case the call has been unmerged (the conference call has finished), combined with the other 2 possible cases where the call should also be inserted into the main call screen page I mentioned before: 1) the group details are displayed and 3 seconds passes until it is hidden and 2) the group details are displayed and the user manually hides them before the 3 seconds passes, should definitely work :)
