Make sure 'map' is defined

Fixes #84

[rbartoli]

I've tested this fix and it works. Is it possible to merge it please?

This fixes the issue, but drops the test coverage. @sokra any thoughts on how we should test the treatment of source maps?

[markdalgleish]

Thanks for the original PR, but I needed to add tests for this for the coverage check to pass.

This issue should now be fixed in v0.15.3.

I've just updated to 1.5.3 (from 1.4.5) and I still have a similar issue:

Here's my webpack.config configuration:

// ...

  loaders: [
     { test: /\.css$/, loaders: ['style', 'css?module&localIdentName=[name]__[local]___[hash:base64:5]', 'postcss'] },

@moretti This looks like a different error. Could you open a new issue?
