    notebook: add newly-pinned tabs at end, not at start
    
    This is slightly nicer, since tabs that you pinned first appear in the
    leftmost position. As a side effect, this also prevents pinned tabs from
    reordering themselves when loading the session.
    
    Fixes #1341
    
    
    (cherry picked from commit 42c2385b62d9b75292574b05009d4f6925f613c4)
