Update REST_Controller.php

I kept having an error with multiple databases per model.  I've added another load database string before the turn of the function... Only solution that seemed to work.

Error Number: 1146
Table 'table_name.api_access_logs' doesn't exist

UPDATE `api_access_logs` SET `rtime` = 0.039106845855713 WHERE `id` =  73
