Fix issue with temporary children introduced by OTP-9064
The temporary child specs are never removed from the supervisor's state, and have they're MFA component set to {M, F, undefined} instead of the MFA passed in the supervisor:start_child/2 call. Subsequent calls to supervisor:restart_child/2 may crash. Stack trace example: {badarg,[{erlang,apply,[gen_server,start_link,undefined]}, {supervisor,do_start_child,2},{supervisor,handle_call,3}, {gen_server,handle_msg,5}, {proc_lib,init_p_do_apply,3}]}
