puppet_agent : newer versions of gpg2 change output format, causing attempts to get gpg keyid to fail

Basic Info
Module Version: 2.0.1
Puppet Version: 5.5.8
OS Name/Version: sles 15

While testing out sles15 support in pe2018.1.5 I use the puppet_agent module to ensure the agent version is 5.5.8. The exec which installs the gpg keys has an unless attribute that is trying to obtain the keyid, but fails due to gpg2.2 having a different output format than the code expected. So this '| cut --characters=11-18' no longer retrieves the keyid when using gpg2.2

Desired Behavior: expected gpg keys to be imported only once
gpg 2.0 output on sles12sp3:
gpg --homedir /root/.gnupg --throw-keyids < /etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
pub 4096R/4BD6EC30 2010-07-10 [expires: 2017-01-05]

Actual Behavior: keys continue to re-import in every puppet run

gpg2 2.2 output on sles15:
gpg --homedir /root/.gnupg --throw-keyids < /etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
gpg: WARNING: no command supplied. Trying to guess what you mean ...
