Thanks for providing this sample, the modification below makes sure that all files have numbers starting with 0, and if there are no certificates in the file no output is created.

awk '
BEGIN {n=0;seen_cert=0}
split_after==1                {n++;split_after=0}
/^-----END CERTIFICATE-----$/ {split_after=1;seen_cert=1}
seen_cert==1                  {print > "trust_root_certificate_" n}
' /path/to/certs.pem
