CRM_Import_DataSource_SQL::postProcess contains a call to $this->set() but the set() function is not defined.

While troubleshooting an unrelated error, I noticed the following code in CRM/Import/DataSource/SQL.php

$this->set('importTableName', $importJob->getTableName());

But there is no set() function defined within the CRM_Import_DataSource_SQL class.

I see that:

class CRM_Import_DataSource_SQL extends CRM_Import_DataSource

But in searching through CRM/Import/DataSource.php I find no set() function defined within the CRM_Import_DataSource class, either.

EDIT: As it turns out, the postProcess() function is never called. The attached patch resolves the problem by deleting the function body, converting it to a stub.
