Bug#43716: Test mysqlbinlog_row_big is failing, needs to be updated
Altered the test to accommodate the new behavior of max_allowed_packet.
Had to disconnect / reconnect the default connection for the new value to register.
Re-enabled certain parts of the test that were commented out and added
some setup / cleanup code to ensure proper reset of max_allowed_packet at the end of the test.
Re-recorded the .result file to account for changes to the test.
