If one task is failing, keep processing the others
Commit fir attachment imported after each file to be sure not to loose any data, when deleting on remote after import for example
- correct `directory_output` value
- mute logger for desired raise exception
- change how the "already imported files" are checked when
"check_duplicated_files = True" :
It occurs that a task o2m field `attachment_ids` returns an empty record
when checked during the `_file_to_import()` method... but only when
the module `autovacuum_message_attachment` is installed !
