fix: Don't show loaded when both filters are disabled

[TheDukeofErl]

Fixes #158. When both of the filters are disabled and unloaded, "Noisetorch unconfigured" will be shown in light blue. This should clear up some user confusion in this case.

I just looked at this and like the result.
Going one step further I was thinking if we should show something similar, when on one hand at least one filter is being set, but no device being selected?

well - at least there are no buttons there in that case. so I'm fine with letting it be like that.

I do have some code written that will reach that state, as well as a related bugfix I noticed while making it. The bugfix should probably go in no matter what. I can go either way on unconfigured vs loaded when filtering is selected but no device is. Technically I guess it would be more correct to show "unconfigured" but it may be a state in which a user is expecting things to be "active" so a red "inactive" may be more applicable. Either way, I'll get the changes on branches in the afternoon so we can decide what to do.

Hopefully you'll still get the notification from this PR :D
