function DefaultConfigTest::testConfigIsEmpty

Tests that core.extension.yml is empty by default.

The default configuration MUST NOT specify any extensions, because every extension has to be installed in a regular way.

Otherwise, the regular runtime application would operate with extensions that were never installed. The default configuration of such extensions would not exist. Installation hooks would never be executed.
