In my case, I export a Program with a mention.

When I try to import this Program, the mention is not imported, with a warning : `There is no entry corresponding to the CDM-fr or Ametys code 'Arts du spectacle' in the reference table 'odf-enumeration.Mention'.`

The problem seems to be in `org.ametys.plugins.odfsync.cdmfr.components.AbstractImportCDMFrComponent._getIdFromCDMThenCode(String, String)`

Mention is an abstract tableref, so it contains nothing, this code should test the different implementations of this tableref (or maybe the `ContentTypeExpression` used should test on the different implementations of the content-type passed ?)
