[fix] Apply fulltextindexed change in the actual index Change of the fulltextindexed attribute of a CWAttribute did actually change anything for already existing entity (but apply to new one). This patch fix this behaviour: * A new SingleLastOperation, UpdateFTIndexOp, to reindex entity whose ftindexation changed during a commit. This data is read from session.transaction_data['fti_update_etypes'] * The SourceDbRDefUpdate operation to store Etype who modify they fulltextindexed of attribute in session.transaction_data['fti_update_etypes']. * A new test is added to check the behaviour
