[FIX] hr_holidays: fix kanban view date format

Issue

	- Install Time Off & Studio
	- Set up your language to English with format date
	  to %d/%m/%y instead of %m/%d/%y
	- Enable Kanban view in Time Off dashboard with Studio
	- Compare Kanban and List view

	The list view dates is correctly formatted but not
	the kanban view dates

Cause

	We use momentjs which doesn't take the user date format
	in account, only the locale.

Solution

	Use a field with datetime widget which handle this case.
