[FIX] odoo: fixes the error when deleting the worksheet template

Steps to reproduce :
- install field service module
- install industry_fsm_report bridge module
- click on configuration
- click on worksheet template
- try to delete more than one record

Issue:
-  error while deleting more than one record

Cause:
- because ,this issue is from base while deleting the model id's

Solution:
- if we write condition for filtering manual models and calling prepare_update()
   method and then non manual models ,then the issue will be solved
