When running in multiple environments, json and junit reporters generate report for only one environment

Description of the bug/issue

When running in multiple environments, json and junit reporters generate report for only one environment.

Steps to reproduce

1. Run parallelly on multiple browsers using Nightwatch. ./bin/nightwatch examples/tests/ -e chrome, firefox --parallel
2. Check the test_outputs folder. The reports only get generated for a single browser.

Sample test

describe('Ecosia.org Demo', function() {

  before(browser => {
    browser
      .navigateTo('https://www.ecosia.org/');
  });

  it('Demo test ecosia.org', function(browser) {
    browser
      .waitForElementVisible('body')
      .assert.titleContains('Ecosia')
      .assert.visible('input[type=search]')
      .setValue('input[type=search]', 'nightwatch')
      .assert.visible('button[type=submit]')
      .click('button[type=submit]')
      .assert.textContains('.layout__content', 'Nightwatch.js');
  });

  after(browser => browser.end());
});
