[FIX] util/models: Fix constrain voilation

before 16.5
https://github.com/odoo/odoo/pull/114352/files#diff-f456849127002cd01a9e2058290e40ae8e5c1d57e15785699f0172400766bcd4R69
there was constraint on field ``action_server_id``
of ``base.automation`` model ON delete restrict
https://github.com/odoo/odoo/blob/d07ffce41df433e51d1239be855cd52867b905e0/addons/base_automation/models/base_automation.py#L34C5-L34C21
which causing issue during upgrade when removing model if contextual
action created for the same server action ``binding_model_id``
https://github.com/odoo/odoo/blob/3a28e5b0adbb36bdb1155a6854cdfbe4e7f9b187/odoo/addons/base/models/ir_actions.py#L35
as below mentioned traceback because due to on delete cascade model
will remove.So, server action will also delete. But server action
is linked to automated action. So, request will block.

For fixing this issue removing the automated action first and
then let the model remove.
