This patch corrects a bug involving a LOAD DATA INFILE operation on a
transactional table. It corrects a problem in the error handler by moving
the transactional table check and autocommit_or_rollback operation to the
end of the error handler.
The problem was an assert was thrown after the operation completed. The
assert found a non-sunk event in the transaction cache. The events in the
transaction cache were added after commit_or_rollack and thereafter nothing
removed them.
An additional test case was added to detect this
condition.
