Update recuperation-enregistrements.gtw

cDaoUserRecord_mymodule_Jx_mydao_Jx is not created at the time the class is declared, and the real name is cDaoUserRecord_mymodule_Jx_mydao_Jx_dbsystem (eg. dbsystem = mysql).

It seems the inheritance is working the other way. cDaoUserRecord_mymodule_Jx_mydao_Jx_dbsystem is inheriting myrecordDaoRecord.
