better filter on trigger event state_change

[marcob79]

adding in event_data the entity_id of input cavuum

[PiotrMachowski]

This event trigger can't be changed in this way - it is used in browser mode:

  is_browser_mod_template_trigger: |-
    {{
      mode_to_handle in ['browser_mod_path']
      and trigger.id == 'state_changed'
      and (
          trigger.event.data.new_state != None 
          and trigger.event.data.new_state.attributes != None 
          and "pathSegments" in trigger.event.data.new_state.attributes
          and browser_mod_path == trigger.event.data.new_state.state
        or
          trigger.event.data.old_state != None 
          and trigger.event.data.old_state.attributes != None 
          and "pathSegments" in trigger.event.data.old_state.attributes
          and browser_mod_path in trigger.event.data.old_state.state
        )
    }}
