refBy should always return something with service calls available

[zoe-codez]

Context

This should be a thing somehow

hass.refBy.label('thing', 'switch').turn_off()

Currently this method returns back an array of objects, so there needs to be some sort of weirdness built on top of that to do aggregation for the service calls

Open question
Resolution logic when multiple domains are returned.

• Attach all methods and attempt to do filtering at runtime?
