output: true broken

[QuentinRoy]

It seems that output: true is broken. While it used to "write all styles to the bundle destination where .js is replaced by .css", it now writes them to the input destination (which is usually not what is wanted).

For example:

import resolve from 'rollup-plugin-node-resolve';
import sass from 'rollup-plugin-sass';

export default {
  input: 'src/index.js',
  output: {
    name: 'Project',
    sourcemap: true,
    file: './project.js',
    format: 'umd'
  },
  plugins: [
    resolve(),
    sass({
      output: true
    })
  ]
};

Produces src/index.css.
