[REV] sale_timesheet_margin: disables onchanges on service products

Revert
"[FIX] sale_timesheet_margin: prevent cost override on product service"

This reverts commit e260a973.

After discussing with thcl-odoo, it was determined that it is better to
revert this commit as it is affecting all service products.
Also the desired behavior is that users should change the cost on
the product form not on Sales Orders
