Describe the enhancement

Currently, like for automations, the condition section in a trigger based template entity is processed before the action part. For automations this makes sense, but for template entities the action part is mostly supporting, and used to perform actions which provide a response to be used in the template entity itself.

By processing the action part before the condition part in a trigger based template entity, you can use the variables created in the action part in conditions, so you don't have to make complicated templates for the state and attributes to prevent the previous valid state to be lost in case the provided variables are not correct.

Use cases

It will make it easier to ensure a valid state and valid attribute values without need to refer to this.state

Anything else?
