[pgpool-committers: 1224] pgpool: Fix bug with load balance in replication mode.

[Tatsuo Ishii]

Fix bug with load balance in replication mode.

When load_balance_mode is off in replication mode, SELECT's should be
sent to master node only, rather than sent to all nodes in an
explicit transaction. Also add regression test case for this. Problem
reported in [pgpool-general: 2038].
