[FIX][18.0] connector_importer: allow sudo for the user to access ir.ui.view model

[yankinmax]

To access ir.ui.view model records the user should have Administration\Settings::base.group_system group assigned.
While the connector.group_connector_manager and connector_importer.group_importer_user don't have such rights.

To reproduce:

1. Go to "Import recordsets" => "Import recordset" => click "Configure source" button.
2. The open_source_config method calls get_config_view_id to fetch the requested view.
3. An access error is raised.

odoo.http: You are not allowed to access 'View' (ir.ui.view) records.
This operation is allowed for the following groups:
	- Administration/Settings
