TYPO3 Core

Given:

- try to install extension "devtools" in its current TER version (check "I know what I'm doing..." dialog)

Expected:

- the extension is not compatible yet, an exception should be visible

Actual:

- an fatal error is thrown, because an array parameter is expected, null is given

Background:

- \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::loadSingleExtLocalconfFiles uses require without method context - thus no argument is available in trace
