      Description

      On SAK-27494 it was originally reported that some tools (like Samigo) could create duplicate gradebook items. However this was this comment here that with this new patch Samigo (Test and Quizzes) caused Deadlock exceptions. I haven't tried to reproduce this myself but I believe it's unchanged from this comment.

      The patch proposed by Brian works. At least duplicated gradebook items aren't saved, but some exceptions are thrown:
2014-12-16 15:54:42,504 WARN http-apr-8080-exec-22 org.hibernate.util.JDBCExceptionReporter - SQL Error: 60, SQLState: 61000
