Remove the proxyPort parameter when creating a bucket
Remove the proxyPort parameter when creating a bucket

The BucketManager doesn't allow creating port buckets anyways and
I found that including this parameter can cause the bucket creation
to sometimes fail with an error message saying a bucket already
exists on a the specified port. This issue omly seems to happen when
creating and recreating buckets quickly.
