Description for ee-6.2.x

When using custom error message for auto fields, the custom error message is not replicated for newly added fields

description for master

auto_fields.js behaves strangely:

• -custom validator is not called when field is empty
• error messages are multiplied (1 for the first field, two for the second, three for the third, etc) this issue disappeared
• the custom error message is not replicated for newly added fields: THIS FIX FIXES ONLY THIS ISSUE

steps to reproduce

• Deploy the attached portlet
  It is a pure view.jsp file which creates a form and instantiate auto fields for the only input field
  with a custom error message. The erro should be fired when the input is empty
• put it onto a page
• Leave the input field empty and press TAB button (on master, write something into the input field and press TAB)
• notice the custom error message
• Add a new field with the "+" button
• Repeat the step
• Consider the default error message (two error messages on master)
