Subject: [PATCH] [BUGFIX] NPE in Index Queue module when no site is selected

In multi site setups a null pointer exception is thrown when opening the
Index Queue TYPO3 module without having a solr-enabled page selected in
the page tree. The NPE is thrown in `::initializeAction()` before the
original handling of the "no site selected" case in `::indexAction()`.

Fixes: 3ea271319 ("[TASK:BP:11.6] Consider queue initialization status")
