Fix supervisor reporting error
When a simple_one_for_one supervisor is shutting down, if one or more of its children fail to terminate within the 'shutdown' timeout, then the following reporting error will occur: * If there is only one child that fails to exit on time, then no supervisor report will be generated. * If more than one child fails to exit on time, then the reporting of 'nb_children' in the supervisor report will be 1 less than it should be.
