setValue error does not provide a stackTrace

[hcmec]

If I try to .setValue on an element that does not exist, I do not get a stackTrace this breaks at. This is more irritating if the .setValue call is in a pageObject
See the #purposelyBroken and setPurposelyBroken() lines below

// Filename: examples/tests/googlePageObject.js
module.exports = {
  'Demo Google search test using page objects' : function (client) {
    var homePage = client.page.home();
    homePage.navigate();
    homePage.expect.element('@searchBar').to.be.enabled;

    homePage.setValue('@searchBar', 'Nightwatch.js');
    homePage.submit();
    homePage.setValue('#purposelyBroken', "Purposely Broken");   
    homePage.setPurposelyBroken(); // calls setValue from a pageObject

    var resultsPage = client.page.searchResults();
    resultsPage.expect.element('@results').to.be.present.after(2000);
    resultsPage.expect.element('@results').to.contain.text('Nightwatch.js');
    resultsPage.expect.section('@menu').to.be.visible;

    var menuSection = resultsPage.section.menu;
    menuSection.expect.element('@web').to.be.visible;
    menuSection.expect.element('@video').to.be.visible;
    menuSection.expect.element('@images').to.be.visible;
    menuSection.expect.element('@shopping').to.be.visible;

    menuSection.productIsSelected('@web', function(result) {
      this.assert.ok(result, 'Web results are shown by default on search results page');
    });

    client.end();
  }
};

// Filename: examples/pages/home.js
const searchCommands = {
  submit() {
    this.waitForElementVisible('@submitButton', 1000)
      .click('@submitButton')
      .api.pause(1000);

    return this; // Return page object for chaining
  },
  setPurposelyBroken() {
    this.setValue('@searchBarPurposelyBroken', "Purposely Broken");
    return this; // Return page object for chaining
  }
};

module.exports = {
  url: 'http://google.com',
  commands: [searchCommands],
  elements: {
    searchBar: {selector: 'input[name=q]'},
    searchBarPurposelyBroken: {selector: '#purposelyBroken'},
    submitButton: {selector: 'input[value="Google Search"]'}
  }
};

actual output:

I have pre-tested the current nightwatch version (1.0.19) with this PR and it works correctly.

Thanks and best regards
