    Fix gtk accelerator mixups by explicitly disabling actions that are not relevant
    
    The issue I found was with File->Print and its variants for various page types.
    They all use the same '<primary>p' as global accelerator. It was possible to
    have gnucash invoke the 'Print Report...' action instead of the 'Print Invoice...'
    action when hitting <primary>p on an invoice page. If no report page was
    open at this point, gnucash would crash. If a report was open, gnucash
    would invoke the print action on that report instead of opening an
    invoice report for the invoice. This looks like a bug internally in
    the gtkaction handling or our improper use of it. However I could
    work around it by disabling action groups before unmerging them.
