Fix key error MQTT binary_sensor when no name is set

[jbouwh]

Proposed change

Setting a name for an MQTT entity has become optional. In cases where no name is set, the device_class is used to derive the name. When an MQTT binary_sensor receives a state it will not process, it cannot assume a name is set for the entity. This PR logs the entity_id instead of the name to solve the issue.
