Fix hangs from loadCommands

[thewilloftheshadow]

Currently, the nodeJS loadCommands handler only looks for the default export and tries to load it as a command, but if there is no default export, it will just hang forever and never resolve (with no error).

Need to find a way to either catch that there isn't a default or make it throw an error instead of hanging.

Another instance where it hangs is recursive imports (e.g. importing from index.js where loadCommands is called)
