This was discovered none other than Bug Catcher Nate, while in the TWiKS
room. That room doesn't have a canonical alias set (yet) and that
exposed some UX problems around aliases in NeoChat.
First, the non-canonical alias isn't shown in the info drawer despite
being the only alias available. This is something that Element actually
does, and now NeoChat does too.
Second, NeoChat will try to copy the room's internal Matrix ID (which is
not that great) to the clipboard because it looks for the canonical
alias. Surprisingly, Element also does this but now NeoChat doesn't.
Create a new module for the room info drawer QML. This also requires moving some QML to LibNeoChat common with other modules. Finally all QML in roominfo is modifed to not depend on app.
