Fixed regression test failure (#254)

* Change the backup_from_standby test item.

Change the backup_from_standby test item because it is not possible
to create a streaming replication with external tablespaces on one localhost.
So I removed command about created external tablespace.
And I used pg_basebackp command to replaced pg_backup_start() and pg_backup_stop().

* Corrected parameter values.
