Shall use context=context here?

No, we want the automation triggered to be with the new context, that way we will be able to attach automation metadata to the context.

Description:
When an automation is triggered, we were re-using the context from the event that triggered the automation. However, this has the unintended side effect that the automation will run with the permissions of the user triggering the automation.
It also would have caused issues in the future when doing machine learning, because although the result of an automation should be linked to the triggering event, it should not be fully attributed. It is the automation that is doing things now.
So to cover this partial relationship I'm introducing a
parent_idforContext. This will allow a context to optionally point at a previous context that caused this context to start, without conflating the concerns that the actions of the automation get attributed to the triggering event.The first thing being done with the context is firing an
automation_triggeredevent, so that it's clear that it's an automation.We need to store the context parent ID in the database. I want to do that, but I want to group a couple of more migration changes together (like increasing event type size), so have commented it out for now.
