Enabling NOTIFICATIONS may lead to errors with NOTIFY_ON (or if it's not present)

Autosubmit Version

master, 4.1.11

Summary

If you create a simple workflow, with just one task, and enable notifications with this:

mail:
    # Enable mail notifications for remote_failures
    # Default:True
    NOTIFY_ON_REMOTE_FAIL: True
    # Enable mail notifications
    # Default: False
    NOTIFICATIONS: True
    # Mail address where notifications will be received
    TO: bruno@blabla.blabla

Without adding NOTIFY_ON to the sole job, you will get:

Successful check job command: nohup kill -0 623 > /dev/null 2>&1; echo $?
Successful check job command: nohup kill -0 633 > /dev/null 2>&1; echo $?

What is the current bug behavior?

Python error.

What is the expected correct behavior?

Nothing, no notification as there is no notify_on.
