buckets still being deleted are not visible anywhere in REST API (was: API pools/default/buckets/ doesn't return any buckets but attempt to create bucket gives: Bucket with given name still exists)

notice, that bug was filled before: MB-6710: Deleting bucket on a cluster gives error "Some nodes are still deleting bucket"

2012-09-22 17:36:57,643] - [rest_client:96] INFO - existing buckets : []
[2012-09-22 17:36:57,650] - [rest_client:1234] INFO - http://10.2.2.60:8091/pools/default/buckets with param: proxyPort=11211&bucketType=membase&authType=sasl&replicaIndex=1&name=default&saslPassword=&replicaNumber=1&ramQuotaMB=1456

{"_":"Bucket with given name still exists"}

test was reproduced manually:
andrei ~/repository/testrunner $ curl --user Administrator:password http://10.2.2.60:8091/pools/default/buckets
[]
andrei ~/repository/testrunner $ curlX POST -d "proxyPort=11211&bucketType=membase&authType=sasl&replicaIndex=1&name=default&saslPassword=&replicaNumber=1&ramQuotaMB=1456" --user Administrator:password http://10.2.2.60:8091/pools/default/buckets

{"_":"Bucket with given name still exists"}

I see the same issue with growing vBucket size as in MB-6711, but new bug is related to that API pools/default/buckets/ doesn't correspond to real situation
