When resolve.sync fails the catch clause prevents any custom importer from running

this logic prevents any custom importer from running, a better way is to return null in case customizedSassOptions.importer is defined to allow it/them to run.

To reproduce just try to import with any custom path format that will not correctly resolve for example a path with a variable like:

@import '~test/${theme}/utils';

it will fail and notice that even after adding

options: {
        importer: [
          function(url, prev, done) {
            console.log('this will never run...');
          }
        ],
       // ...
}

The custom importer doesn't run (while it does after returning null).
