Order of @import-ing files changes randomly

It looks like sometimes the order of @import-s are changing randomly:

D:\localhost\sass-extract-loader-master\examples\basics>npm start

> [email protected] start D:\Downloads\sass-extract-loader-master\examples\basics
> webpack 1>/dev/null && node dist/app.bundle


--- Style Varibles ---

global:
  $value:
	type:        SassString
	value:       OK
	sources:
	  - D:/localhost/sass-extract-loader-master/examples/basics/src/_style1.scss
	  - D:/localhost/sass-extract-loader-master/examples/basics/src/_style2.scss
	expressions:
	  - 'OK'
	  - 'NOT OK'



D:\localhost\sass-extract-loader-master\examples\basics>npm start

> [email protected] start D:\localhost\sass-extract-loader-master\examples\basics
> webpack 1>/dev/null && node dist/app.bundle


--- Style Varibles ---

global:
  $value:
	type:        SassString
	value:       NOT OK
	sources:
	  - D:/localhost/sass-extract-loader-master/examples/basics/src/_style2.scss
	  - D:/localhost/sass-extract-loader-master/examples/basics/src/_style1.scss
	expressions:
	  - 'NOT OK'
	  - 'OK'

The content of style.scss:

@import "style1";
@import "style2";

The content of _style1.scss:

$value: 'NOT OK';

The content of _style2.scss:

$value: 'OK';

It should return 'OK' as the value of $value, but as it can be seen, _style2.scss gets loaded before _style1.scss in the second run.

(I'm not sure, whether this is an issue with sass-extract or sass-extract-loader. I used sass-extract-loader's "Basic" example)

@bencergazda there was an undefined behavior bug related to the order of the extracted variables that in my tests appeared about once every 20 run (but this can be completely random). This is now fixed in 0.5.3, thank you for finding and reporting it!
