query_supervisor: timeot limit works only onece per connection

When the timeout limit breaks a query, then it wont work for further queries within the same connection. You can check it with pgadmin and any haf database:

1. execute select * from hive.blocks; - a timeout limit will break a query
2. execute once again select * from hive.blocks; (it is important to use the same connection as the first time), now tuples limit is reached, timeout does not work
