Fix AJAX tests to catch WPAjaxDieContinueException

The tests were catching WPAjaxDieStopException but wp_send_json_error()
actually throws WPAjaxDieContinueException.

Fixed in:
- test-class-ajax-security-base.php (2 occurrences)
- test-class-ajax-security-aioseo.php (1 occurrence)
- test-class-ajax-security-yoast.php (1 occurrence)

This fixes the 4 test errors:
- Ajax_Security_Base_Test::test_verify_nonce_or_fail_invalid
- Ajax_Security_Base_Test::test_verify_capability_or_fail_non_admin
- Ajax_Security_AIOSEO_Test::test_verify_aioseo_active_or_fail_not_active
- Ajax_Security_Yoast_Test::test_verify_yoast_active_or_fail_not_active
