fix: handle missing launch templates #99

Closed js-timbirkett closed 3 years ago

js-timbirkett commented 3 years ago

We recently moved from Launch Configurations to Launch Templates and had instances without LaunchTemplate configuration in an ASG that used LaunchTemplates. This resulted in an error when trying to compare launch template versions on those instances.

This PR fixes that and also fixes up a small bug in plan output.
