Role creation fails on first invocation.

[trieloff]

When I'm running lein lambda install dev, the process fails the first time during role creation with following error message java.lang.IllegalArgumentException: No matching field found: getRole for class clojure.lang.PersistentArrayMap. On the second try it works, albeit with a warning message: Note! Role salvador-dev-role already exists.

Thanks for noticing! The role was created successfully but there was a bug in code. The arn of the created role was not returned correctly. I fixed this and released version 0.4.1.

The default behaviour of the plugin is to skip creation of role and s3 bucket if they already exist. It seemed that is something people usually need. However, if there is a need to make this configurable that could be implemented too.
