Property 'getUrl' is required when using MQTT

[ronald8192]

Describe the bug
My understanding is getUrl is only used for the 'pull' way. But when I config MQTT, it still ask for getUrl:

[1/4/2022, 11:30:05 PM] [BedRoom] Initializing HTTP-TEMPERATURE accessory...
[1/4/2022, 11:30:05 PM] [BedRoom] Property 'getUrl' is required!
[1/4/2022, 11:30:05 PM] [BedRoom] Aborting...
[1/4/2022, 11:30:05 PM] [BedRoom] Accessory HTTP-TEMPERATURE returned empty set of services; not adding it to the bridge.

If I give it a getUrl, it can connect to the broker but it still getting the value from getUrl instead of MQTT

[1/4/2022, 11:32:18 PM] [BedRoom] Initializing HTTP-TEMPERATURE accessory...
[1/4/2022, 11:32:18 PM] [BedRoom] MQTT connecting to broker...
[1/4/2022, 11:32:18 PM] [BedRoom] MQTT Connected!
[1/4/2022, 11:32:18 PM] [BedRoom] Subscribing to existing topic: BedRoom/temperature
[1/4/2022, 11:32:18 PM] [BedRoom] MQTT successfully subscribed to topic 'BedRoom/temperature. Granted [{"topic":"BedRoom/temperature","qos":1}]'

Expected behavior
Expected the getUrl property is optional or will be ignored if mqtt config is present.

To Reproduce

1. Setup mqtt server
2. Connect to it using below config
