createBucket request fails with 409 (conflict), but doesn't throw

[mxcl]

When making a create bucket request for an already existing bucket the future succeeds but the operation in fact failed.

Stepping through the framework code in a debugger the first (or second) HTTP request is a 409, but the future is not rejected.

[mxcl]

let createBucketRequest = S3.CreateBucketRequest(bucket: bucket)
return try s3.createBucket(createBucketRequest)

@mxcl Code in here was so old, surprised it worked at all. I've just updated it with latest from aws-sdk-swift if you want to give it another go.
