    revert part of 'warn on load when a document binds an event to a macro'
    
    i.e.
    commit b3edf85e0fe6ca03dc26e1bf531be82193bc9627
    Author: Caolán McNamara <caolanm at redhat.com>
    Date:   Wed Aug 7 17:37:11 2019 +0100
    
    because then extensions that add a entry to menus results in menu
    entries that cannot run in the start center where there is no document.
    
    If allowed when there is no document, it would still result in the
    odd behaviour that such menu entries would not work in a document which
    contained macros or macro-calls if permission was denied to run them
    
    Add a similar check instead to SfxEvents_Impl::Execute
