[AWS] Scan fails with "Error [TypeError]: AWS[serviceName] is not a constructor"

This seems to be a regression, earlier discussed in here: https://github.com/aquasecurity/cloudsploit/issues/2085.

The error is:

```
/var/scan/node_modules/aws-sdk/lib/request.js:31
throw err;
^

```

It seems as if the changes related to CodeStar plugins made in https://github.com/aquasecurity/cloudsploit/pull/2130/commits were rolled back in https://github.com/aquasecurity/cloudsploit/commit/79b1f00d3d538bb84773d2069522840bd5c5b209#diff-003665623877ad886ae62d0768d144a09c5f4bcc54ca40cb3bd3c194f4337e51, and scans fail again.

Start at collectors/aws/collector.js around lines 88, 109, and 139, then compare the CodeStar changes in PR 2130 with the rollback commit and issue 2085. Reproduce the AWS scan failure and confirm that scans complete without the AWS[serviceName] constructor error.
