CASTOR-4839 tapeserverd: task injector should decide on closing the session earlier

Added a the new criteria (less that half the work asked for) for ending the session for migrations.
The symetric for recalls is not possible currently as we do not know the file size beforehand in recalls (it is found out from data on tape).
