[Fix] hr_timesheet: task for view

Improves some aspect of timesheet for a better usability:
Rename "Subtask Planned hours" into "Subtasks" AND put "hours planned" next to the hours as units
changes track visibility of Deadline Planned hours so that a message will be generated when those values are changed.
Progress : it was possible to to have a progress higher than 100% when more time have been spend that the planned hours, but it doesn't reely makes sence for a progress bar.
Remaining hours should be editable: it is now possible to edit the remaining hours if needed, the field planned hours is updated in this case to keep informations consistent.
Also remove the default values of description for the subtasks when it was taken from the parent task name in some cases.
