Wrong label ID for field

Problem/Motivation

In DEV console I see error: "The label's for attribute doesn't match any element id. This might prevent the browser from correctly autofilling the form and accessibility tools from working correctly. To fix this issue, make sure the label's for attribute references the correct id of a form field."

Steps to reproduce

Open custom form with International Phone field.

Proposed resolution

I propose patch to fix discrepancy.
