TYPO3 Core

Steps to reproduce:

• Setup a plain new dummy installation
• Login to backend
• Go to install tool
• Go to Configuration presets, Development / Production settings and select "Development".
• Go to Update Wizard.

ExtJS console shows the following error:

DB error
exec_SELECTquery
caller    TYPO3\CMS\Core\Database\DatabaseConnection::exec_SELECTquery
ERROR    You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1

This is caused by TYPO3\CMS\Install\Updates\RootTemplateUpdate::findRootLevelPages() which should return NULL for empty root level pages, but returns array().
