Fix Error handling following DB Package upgrade

[seamuslee001]

Overview

We recently upgraded the DB package such that any DB_Error class error would actually satisfy the is_callable([$ei, 'getCause']) now because there has been __call function declared https://github.com/civicrm/civicrm-packages/blob/master/DB.php#L1010

Before

E-notice error message about undefined function getCause for DB_Error class see https://test.civicrm.org/job/CiviCRM-Core-Edge/CIVIVER=master,label=test-3/4/testReport/(root)/CRM_Export_BAO_ExportTest/testExportDeceasedDoNotMail_with_data_set__1/ as an example

After

No e-notice error message
