Remove "Not Correctly Pronounced" button from Trainer Session interface.
Review Request #113472 - Created Oct. 27, 2013 and submitted
Currently there are two buttons, "Not Correctly Pronounced" and "Retry Later" in the interface for a trainer session. These buttons have functionalities which are very slightly different, thus making one of these buttons redundant. This patch, removes the "Not Correctly Pronounced" button, while adding its functionalities to the "Retry Later" button.
