macOS 10.12 and 10.13 IB gem creates two windows on startup #93

When loading the osx sample app from the IB gem there are two instances of the window created. One is properly linked with the NSWindowController and the other one is directly behind and is not linked to any NSWindowController.

It looks like the 'visible at launch' box was checked in Interface Builder which was causing two windows to be created. I'm not sure why the second one was built but unchecking the 'visible at launch' box fixed the problem.
