[BUGFIX] Properly merge RequireJS configuration

If PageRenderer->addRequireJsConfiguration() is consecutively called,
the configuration is now properly merged by using
array_merge_recursive(). The previously used
ArrayUtility::mergeRecursiveWithOverrule() overrode any previously set
keys of the numeric array which broke the configuration.
