Page URL key and block identifier already exists after re-creating database

Errors listed below occurs when we drop magento database and let system to re-create it (refreshing the page). 

First page refresh:

```Error in file: "/var/www/magento/app/code/core/Mage/Cms/data/cms_setup/data-install-1.6.0.0.php" - A page URL key for specified store already exists.```

Second page refresh:

```Error in file: "/var/www/magento/app/code/core/Mage/Cms/data/cms_setup/data-install-1.6.0.0.php" - A block identifier with the same properties already exists in the selected store.```

This is annoying especially with EcomDev/PHPUnit module (the Magento unit tests), because EcomDev seperates database by creating his own for loading data for tests. 

QUICK WORKAROUND but is useless on Continuous Integration:
To re-create database just remove / rename module. After successful install restore the CleaverCms.
