[pgpool-committers: 6000] pgpool: Fix extra test failure of extended-query-test/disable-load-bala

[Tatsuo Ishii]

Fix extra test failure of extended-query-test/disable-load-balance-off.

There were two reasons why the test fails.

1) when disable_load_balance_on_write = off, parse_before_bind should
   have not be called at all. So fix this.

2) the test data tests/disable-load-balance-off.data did not set
disable_load_balance_on_write = off.
