    MainWindow: connect to notify::active-tab at the end of initialization
    
    When the signal is sent, all latexila widgets/objects must have been
    created (at least those used in the signal handler). To be sure that all
    objects are created, connect to the signal at the end of the MainWindow
    initialization. And set_tab_group() after connecting to the signals, so
    if the notebook already contains a tab, the signal handlers will be
    called.
    
    This commit has normally no visible effect in latexila, it is just to
    have safer and more future-proof code.
