[FIX] web: deadlines are not visible in day/week calendar views

Due to commit odoo/odoo@0150141756addb9782b4978de904224cf65e7501
when the widget calendar is initialized with date type record for
date_start and without all_day mapping events aren't shown on day/week
views. This is because all day zone isn't visible when all_day mapping
is not set.

After this commit, we show the all day zone also when the date_start is
a date type.

Steps to reproduce:
* Go to Project App
* Select/Create a project
* Select/Add a task with a deadline
* Return to project
* Select calendar view
* Select week view (of the deadline) => BUG

closes odoo/odoo#51818
