[FIX] hr_timesheet : round time on task

Steps :
- Install Sales & Timesheets
- Timesheets > Settings > Time Encoding :
	- Min duration : 60 min
	- Rounding up : 15 min
- Create a Project P
- Create a Product S :
	- Product Type : Service
	- Service Invoicing Policy : Timesheets on tasks
	- Service Tracking : Create a task in an existing project
	- Project : P
- Create a Sales Order SO and add S
- SO > 1 Tasks (smart button) as T > Timesheets (tab) > Add a line :
	- Employee : Mitchell Admin
	- Duration : 0

- Timesheets > Start :
	- Time : 1:09
	- Project : P
	- Task : SO:S
- T > Timesheets (tab) : Note Time = 1:15 (Min duration + Roundup)

- T > Start and Stop
- Confirm Time Spent Wizard : Note Duration = 1:00 (Min Duration)
	- Duration : 1:09
- Save and T > Timesheets (tab) : Note Time = 1:09

Issue:
- Unconsistent behaviors :
	The time is rounded when using Timesheets' timer and from Task's timer to Confirm Time Spent Wizard
	but it is not rounded when confirming the Wizard.

Fix:
- Round it in when confirming the wizard too.
