UI translation

[martijnmegens]

Not sure if it's a bug, but I noticed while translating the UI, I had problem translating certain collection.
Users and Comments I couldn't translate (could not insert "labels > plural > en" etc etc), while it worked with Posts, Pages and Projects.

I noticed that Users and Comments didn't have "export" before the line: "const Users: CollectionConfig = {"
when I add "export" it all works :-) but I guess you have done that for a reason...

Is it abug, does my fix break stuff? I too much of a novice to find out myself :-(
