Exclude items without root streamers.

Do not attempt to write decorations for which necessary root streamers are missing.

The problem may occur when trying to write AODs in the same job which also runs InDetPhysValMonitoring.

(In principle it would be possible to add the necessary root streamer, but one decoration uses vectors of std::tuple for which root seems to create an incorrect streamer. The latter problem can be worked around, but if there is no need to have these decorations in the AOD, it is rather recommended to not support decorations using non-simple types)
