unable to recognize prepared stmt for encoded_plan + system catalog

./testrunner -i /Users/ketaki/imp_scripts/ini/n1ql/here.ini primary_indx_type=GSI,nodes_init=2,doc-per-day=1 -t tuqquery.tuq_system.SysCatalogTests.test_prepared_buckets,named_prepare=catalog_prepare,encoded_prepare=True

System catalog queries still fail , rest work as expected.
