[IMP] sale_timesheet: remove duplicate field definition

The field `project_time_mode_id` on res.company is
already defined in project module. This came from the
good old days where timesheet was not totally depending
on project.
In sale_timesheet, the field was redefined, and a hack
with xml id was done. It is time to remove this crap.
