upgrading from v2.8.0 to v2.9.0 on S3 causes BucketAlreadyOwnedByYou error

[bacongobbler]

In v2.8.0 and in previous versions, we erroneously created the database bucket in the default us-east-1 region regardless of the set region. In v2.9.0 we corrected this, but when you upgrade from v2.8.0 to v2.9.0 you are greeted with this error:

/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/002_create_bucket.sh
Traceback (most recent call last):
  File "/bin/create_bucket", line 28, in <module>
    conn.create_bucket(bucket_name, location=region)

<Error><Code>BucketAlreadyOwnedByYou</Code><Message>Your previous request to create the named bucket succeeded and you already own it.</Message><BucketName>workflow-database-29</BucketName><RequestId>B949AE55E09300BE</RequestId><HostId>7vVUWxtbxxrSBKPEqPQnzdFFCnMdC4mmLrCnKmbU05nz4tjcdk/BWSGATVuFoUN9sO/It4sH9X4=</HostId></Error>

This is because the bucket lookup code now logs into the specified region, and becuase it is not there it is not found. When boto attempts to create the bucket, it is met with this error because the bucket already exists in another region.
