Fix matter exception NoneType in set_brightness for optional min/max level values

[neocolis]

Proposed change

• Fixes NoneType exception being thrown when trying to dim matter lights (Tapo S505D light in this case) when the minLevel and maxLevel values in LevelControl are not defined.
• Fixes incorrect minLevel value for get_brightness as the spec lists a minimum value of 1 as the minLevel for LevelControl.

Thanks!

The devices I tested so far all had these min/max values defined so missed this.
I assume you tested on you device and it now works as expected!
