The current logic is swapped. MenuAttributes::aImageId can be
only handled by SvFileInformationManager, while the menu item
command is what might be (in case of .uno command) handled
by CommandInfoProvider.
This gone wrong in tdf#96059 which wrongly assumed that
GetImageFromURL is equivalent to what's provided by
CommandInfoProvider (so other places should be checked too).
