This tries to fix two little mistakes  :
 - the `expectException` should never be used twice in a test (because it does not actually try/catch, the first exception will stop the execution of the test and will be catched outside).
 - the piece of code that is expected to throw an exception should always come last in the test (because again, no try/catch, so any line after the throwing line will not be executed).
