Not using the latest css as source

[Tim Coysh]

Description

The manifest.json file being merged with, is containing the correct hash of the compiled SCSS.
Manifest.json is updated (according to filemtime) but not with the correct rev.
Is it possible to fancylog the md5 rev is generating?

	const rev = require('gulp-rev');
	gulp.src([pkg.paths.dist.css + pkg.vars.cssName], {base: 'public/'})
		.pipe(rev())
		.pipe(gulp.dest('./public/'))
		.pipe(rev.manifest('templates/manifest.json',{merge:true}))
		.pipe(gulp.dest('./'));
	$.fancyLog(' -> Processed ['+pkg.paths.dist.css + pkg.vars.cssName+']');```


#### Steps to reproduce
Run `gulp static-assets-version`
