Can't join tab-completed room names.

[emilio]

Steps to reproduce

1. Try to switch rooms by using /join #room-name from the current chat.
2. Autocomplete the room name using the tab key. So, if I want to join the #developers room, I type /join #d<tab>
3. Press enter.

Outcome

What did you expect?

Joining the room.

What happened instead?

Command error
Usage: /join <room-address>

I think this used to work at some point in the past.

Will you send logs?

No

(Happy to send logs if needed, I just thought that they shouldn't be needed since it is trivial to reproduce)

I'm happy to try fixing it btw (vacations are going to be a bit boring due to covid anyways :/). Any pointer to the relevant code would be appreciated, but otherwise I'll try to look into this after Christmas :)

Though also keep in mind that you can only tab complete rooms you're already in so it's a little moot for this to function

Well, /join not only joins, it also also switches to that room. I use it to not have to use the mouse to switch to another room I'm already in.

Why not use the dedicated quick switch shortcut

Ctrl/Cmd + K
Type your query
Hit enter

I didn't know that shortcut :-)
