Affects - latest master - due to adodb upgrade

Get error:

[WAR] 72 (lib/errors.php:745) Invalid values parameter sent to get_recordset_sql.
Call stack (most recent first):

    log_message("Invalid values parameter sent to get_recordset_sql...", 8, true, true) at /home/robertl/htdocs/mahara-devel/mahara/htdocs/lib/errors.php:95
    log_warn("Invalid values parameter sent to get_recordset_sql...") at /home/robertl/htdocs/mahara-devel/mahara/htdocs/lib/errors.php:745

    get_records_sql_array(" SELECT aa.artefact, a...", "") at /home/robertl/htdocs/mahara-devel/mahara/htdocs/artefact/lib.php:1120

The problem is now that adodb is upgraded it is more strict on what it accepts as $values

Needs to be empty array() and not empty string
