Child questions now clear successfully when the parent is cleared

When a user clears a parent question, any hidden child question targeted by a rule that invokes the clearValue() function now clears successfully without error. The Clear Item API (v2.0) has been updated to handle hidden items by supplying the appropriate data classification during validation. As a result, rule-driven clear actions complete as expected, and the UI no longer displays an error.
