Fix incorrect globs in Windows OS terminals (cmd, powershell)

[Aspirin4k]

NodeJS automatically parses globs in argv, but the actual algorithm depends on shell.
Consider following example:

node .\index.js ..\..\Graphics\*.png

In WSL it will lead to files containing following

[ '../../Graphics/Button.png',
  '../../Graphics/ButtonCulprit.png',
  '../../Graphics/ButtonCulprit_selected.png',
  '../../Graphics/ButtonWide.png',
  '../../Graphics/ButtonWide_selected.png',   
  '../../Graphics/Button_selected.png',
  '../../Graphics/LabelSelectCulprit.png',
  '../../Graphics/Login.png',
  '../../Graphics/Modal.png' ]

While both in powershell and cmd files will contain

[ '..\\..\\Graphics\\*.png' ]

See nodejs/node#15529

Current logic inside generate function tries parsing glob only if it's not array (in reality it's array that contains single element)
