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}]}
