Handle loaderUtils.getOptions returning null

[joanamelo]

Hello there!

My project has several dependencies that use preprocess-loader, so the project build is failing with 0.2.1, the most recent version at the moment.

The problem is that the code is creating query = loaderUtils.getOptions this, but this.query is undefined, so query is not an object, it is null. So it throws error is accessing query.ppOptions: TypeError: Cannot read property 'ppOptions' of null.

I've had the same problem with the latest update to 0.2.1 and it was caused by a loader that have no options.

Failing in 0.2.1:

{
	loader: 'preprocess-loader'
}

I fixed the problem, by simply adding an empty options object:

{
	loader: 'preprocess-loader',
	options: {}
}
