**Describe The Problem:**
<!-- A clear and concise description of what the issue is. -->
The plugin is trying to set the default doorbell message even when the feature is disabled.

I do not have a protect doorbell and have configured my homebridge user as viewer only (RTSPS was manually configured on all cameras and works perfectly). I was noticing when starting homebridge that the following log message is displayed...

```Unable to set the default doorbell message. Please ensure this username has the Administrator role in UniFi Protect.```

Since I don't have a doorbell I tried enabling the feature options `Disable.Doorbell.Messages` and `Disable.Doorbell.Messages.FromDoorbell` but the error message is displayed in the homebridge log each time homebridge is (re)started.

So it seems like the plugin is still trying to set the default doorbell message even when the feature is disabled. This isn't really causing any actual issues but I thought this was strange and is probably not intended.

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
Set the feature option `Disable.Doorbell.Messages` and make your user viewer only. Restart homebridge and observe the error message printed in the homebridge logs.
