NCBC-557: NullReferenceException in Queries when IBucket.CreateQuery(...)

is called. Fixes a bug where if you create a View query via CreateQuery and you
do not provide a subsequent call to set the BucketName, a NRE will be
thrown. Now the client will use the IBucket.Name property to set this
field.
