revert part of 'warn on load when a document binds an event to a macro'

i.e.
commit b3edf85e0fe6ca03dc26e1bf531be82193bc9627

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
