Removed the destruction of the bucket allocator prior to

clearing the transaction pool.  The bucket allocator will
now get destroyed when apr_pool_clear() invokes its cleanup
callback.  With the old logic, memory corruption was possible
if the pool contained any brigades that referenced any
buckets allocated from the bucket allocator.
