Fix Report State for Alexa Brightness Controller

[lucasweb78]

Description:

The Report State for Alexa.BrightnessController fails because it assumes brightness is included in the entities properties at all times. This is not the case, brightness is only included when the light is on.

I think this was a mistake, the assert would always exit with a success if the first property was not the one being asserted. This fixes that so all properties are checked and at least one must match the assertion.
