Call Rails.ajax without beforeSend

[ta1kt0me]

When we call Rails.ajax outside rails-ujs.js, we must define beforeSend even though it's empty function. I think Rails.ajax is not private api so it's more useful.

before

    Rails.ajax({
      type: 'get',
      url: '/',
      beforeSend: function() {
        return true
      },
      success: function() {
        // do something
      }

after

    Rails.ajax({
      type: 'get',
      url: '/',
      success: function() {
        // do something
      }
