No files found to match exits with code 3

[Th3S4mur41]

When working with filter (I use a filter to only verify staged files), html-angular-validate throws an error when there is no file to verify.

        htmlangular: {
            staged: {
                files: [
                    {
                        expand: true,
                        src:[
                            '**/*.html'
                        ],
                        filter: function(filepath) {
                            // do some filtering
                            return found;
                        }
                    }
                ]
            }
        },

Unable to perform validation
html-angular-validate error: No files found to match
Warning: Task "htmlangular:staged" failed. Use --force to continue.

Aborted due to warnings.

It should just display a message like "No Files specified" (behavior from guntify-eslint) instead and not abort with an error
