Notifications: Discord: Adding tag id resets webhook URL

Version 6.10.3 2022-06-14

Repro:

1. Go to notifications settings

2. Go to the discord settings part

3. Add webhook URL 

4. Apply

5. Done

6. Go back to notification settings -> Discord

7. Add tag id -> Apply

Observations:

All settings except "Agent function" are reset when saving tag id. It also happens if you set the tag id and webhook URL in the same step.

For now, I'm just not setting the tag id.
