Fix test_decoding test case's check that slot has been dropped.

hlinnaka · hlinnaka · commit afd0fcbc5d42 · 2014-05-16T11:34:46.000+03:00
pg_stat_replication shows connected replication clients. The ddl test case
never has any replication clients connected, so querying pg_stat_replication
is pointless. To check that a slot has been dropped correctly, query
pg_replication_slots instead.
