Sensors show "unknown" until first connection

[joshuaspence]

The connected binary sensor and connection count sensor both report a value of Unknown until the first client is connected. I would have expect the binary sensor to report False and the regular sensor to report a count of 0. This seems to happen because StreamServerComponent::publish_sensor is only called from StreamServerComponent::accept and StreamServerComponent::cleanup.

As a workaround:

esphome:
  on_boot:
    priority: 600
    then:
      - lambda: |-
          id(stream_server_connected).publish_state(false);
          id(stream_server_connections).publish_state(0);

Nice catch, thanks!
