VoiceState.channel_id None when it shouldn't be

[sasjafor]

I have written a simple bot which reacts to voice state updates.

Now when I switch from a normal voice channel to a voice channel with "Connect" permission restricted on discord, the field VoiceState.channel_id is None. But when I already am in that channel, the channel_id is Some and the bot can join the channel.
The bot has the necessary "Connect" permission, and it can join when I have a channel_id to pass.

Serenity version: rev = "722e1cc" on branch v0.6.x (because of issue with openssl 1.1.1)

Rust version (rustc -V): rustc 1.33.0 (2aa4c46cf 2019-02-28)

Minimal test case if possible:

• Discord Server with two voice channels
  • One normal
  • One with "connect" permission restrict for @everyone
• Give "connect" permission to bot
• Join normal channel
• Switch to restricted channel
• Check voice_state.channel_id from fn voice_state_update

EDIT: On a different server with the exact same settings, it seems to work without problems. However, I have written a very similar bot in JS using discord-js and that one can retrieve the channel id and join when doing the exact same test (where the bot using serenity fails), with the same settings on discord.

I can confirm that it doesn't happen on version = "0.5.13". Luckily the docker rust:1.33 image can build serenity without openssl issues.

Until it is fixed you can also use this trick to fix the issue #394 (comment)

(Just to let you know if you run the binary build in docker on a machine with another openssl version it may segfault)

I tried and could not reproduce this (on 5fa5dbf), neither on the new nor old VoiceState. While the old being the one grabbed from the cache prior updating it.

I added help_wanted as I would like other people to try to reproduce this because I could not.
