[FIX] mrp: remove time off for a test

Since [1], a global time off is created in the demo data. Its date is
"today + 8 days". In `mrp`, the test `test_workcenter_timezone` tries to
plan some work orders for the next Monday:
https://github.com/odoo/odoo/blob/06e33207cdc6608e629a316fdddc35a15e08a3ad/addons/mrp/tests/test_order.py#L1882-L1883
So, if you install the demo data of `hr_holdiays` on Sunday and run the
test the day after, the global time off will prevent the slot
reservation by the work orders (and so it will lead to a failed test).
