event.fire and state.set send context if provided

[dlashua]

Test with:

from homeassistant.core import Context


@state_trigger(['input_boolean.test_1'])
def test_state_trigger(**data):
    log.info(data)
    new_context = Context(parent_id=data['context'].id)
    state.set('binary_sensor.test', 'on', context=new_context)

@state_trigger(['binary_sensor.test'])
def test_context_sent(**data):
    log.info(data)

@event_trigger('PYSCRIPT_TEST')
def test_event_trigger(**data):
    log.info(data)
    new_context = Context(parent_id=data['context'].id)
    event.fire('PYSCRIPT_TEST2', context=new_context)

@event_trigger('PYSCRIPT_TEST2')
def test_context_sent_event(**data):
    log.info(data)

data logged by test_context_sent_event and test_context_sent should show parent_id of the received context.
