Title: Prevent SQL Exception When Regenerating Session ID

RE: #2491

Added a value (empty string) for the `data` column when inserting a new row into the session table; the `data` column does not allow null values nor does it have a default value assigned so the CDbCommand::insert() method was throwing an exception when the SQL command failed.
