    session: Emit session-opened-failed on session failures
    
    We used the same signal (session-start-failed) when we had both session
    starting and opening failures.
    
    This may lead to wrong behaviors, so let's introduce another signal to
    notify such state.
    
    
    (cherry picked from commit 2f9afacd494311b8b7393848fec59bc8df7520b7)
