Fix(server): Remove unused loadModels()

[simison]

Remove unused loadModels() from app.js, as it doesn't seem to be used anywhere.

— or am I missing something?

It was added here: edb6234

I can't remember if we ever used this method, but I think the intention was to provide it for use where the server-side app module is accessible, but the mongoose module might not be. I'm not 100% sure on this though, and I've verified that this change wouldn't break anything (from what I can tell).

@lirantal Any insight into this?

I added it as a helper function back then, we can remove it.

👍 Thanks for explaining & merging.
