Title: Add SAG plate dilution gives error fix #26

Correcting the error shown when trying to add a new SAG plate dilution. This error was shown because the class SAGPlateDilution doesn't have any extracted_cell attribute group_id_keyword='sag_plate__extracted_cell__sample__id' istead of group_id_keyword='extracted_cell__sample__id'
