[BUG] Update monitor reset trigger condition

[dominiclapointe]

Describe the bug
When updating a monitor to change any value then saving it, all the associated triggers condition get reset (loose their actual value). For now we can only update monitor doing raw elastic query.

To Reproduce

1. Create a monitor
2. Create a trigger
3. Set a trigger condition
4. Edit the monitor (name or any fields)
5. Look at the trigger condition, which will be reset

Expected behavior
Being table to update monitor without loosing trigger values

Screenshots
If applicable, add screenshots to help explain your problem.

Versions:

• Kibana 7.2
• ElasticSearch 7.2
• Opendistro Alert v1.2.0.0
• Opendistro Kibana Alerting plugin v1.2.0.0

Thank you

Any updates on this? Makes it impossible to add triggers.
