Fix poorly formatted automations

[balloob]

Description:

Automation editor would be prevented from writing automations if the user had copy pasted some automations over to automations.yaml but forgot to add an ID (as per the instructions).

Now, if we see an automation without an ID, we'll add one.

Example entry for configuration.yaml (if applicable):

config:
automation: !include automations.yaml
