  File "/odoo/lib/python3.12/site-packages/odoo/addons/account_check_deposit/models/account_check_deposit.py", line 301, in validate_deposit
    move = am_obj.create(deposit._prepare_move_vals())
                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/odoo/lib/python3.12/site-packages/odoo/addons/account_check_deposit/models/account_check_deposit.py", line 257, in _prepare_move_vals
    ).id
      ^^
AttributeError: 'NoneType' object has no attribute 'id'

We get this stacktrace in account_check_deposit. Couldn't reproduce but I believe this code should fix the stacktrace and let us fallback on company_id.transfer_account_id.
