Calls to socketsJoin() should use channelRoom() from util.js

[chancis]

Calls to socketsJoin() when creating or joining a channel currently harcode the channel:{channel.id} string despite the fact there is a helper function in util.js for this purpose.

These calls are found in channel/create.js line 44, channel/join.js line 40, and user/reach.js line 49.

They should use the channelRoom helper function from util.js, like for example in message/send.js line 41. This will make the code easier to maintain should changes to the channel name string format ever be needed.

@darrachequesne I've prepared a PR to fix this issue - I can create a fork or you could give me permissions to push my branch?

Good catch! Could you please open a pull request?
