AWS master yaml test

Invalid YAML: 'aws-containerize' job needs 'aws-test-java' job, but 'aws-test-java' is not in any previous stage.

The AWS check for 'true' caused the aws-test-java stage to not be included. By using a check of AWS being set to '1' the stage will now be included.

This is a small change. updating $AWS == 'true' to $AWS == '1' in the gitlab-ci.yml
