Channel permissions not updating on permission being removed

[joelaw9]

It seems that the channel objects bot.channels don't update their permissions when a channel specific role/member permission is removed. Version used is 2.4.2.

For example: If I add botRole to #testchannel and then check the Read Messages permission it will show as such in the channel._permissions. Any non-deletion updates to any of the permissions is reflected accurately. But if I delete botRole from #testchannel then it will retain the latest permission state which is then inaccurate.

Not a big one, but it still seems to be an oversight.

Thanks, all of that needs a change. I'll be working on it soon.
