EC2: Cleanup of Security Group and Keypair tasks are skipped

[klaphi]

Problem

The destroy.yml of the EC2 driver uses a wrong execution order. The tasks Write Molecule instance configs will immediately change the condition of the block. As soon as variable is cleaned all remaining tasks of the block will be skipped regardless of their when conditions. The cleanup tasks of for ephemeral security groups and keys will be skipped and the resources will stay.

Solution

Moving the tasks Write Molecule instance configs to the end of the destroy block. With that all destroy tasks will be executed and resources will be wiped.
