Hide the "X in voice" button.

I was in a community server and went to go to another channel, only to see a button that said “1 in voice” at the bottom of the channel list. 

I hid all the VC channels. I don't participate in VC. I don't even want to know that it exists. Stop trying to push it on me. Don't show this if we don't opt in to VC channels, or don't opt in the channel that does have someone in it.
