[FIX] base: delete cascade value mapping on server action deletion

When deleting a server action, its fields_lines were not deleted.
It causes an issue for example in this case:

Create a new custom field on any model
Create a server action with
Action To Do: Write on a Record
Base model: model of the custom field
Add a line in the value mapping,
using the custom field you just created

Delete the server action

Delete the custom field => Throws an error because
required field col1 is not defined
on the ir_server_object_lines object
