[TASK] Call getDomainStartPage without third parameter

The third parameter in PageRepository->getDomainStartPage
is not used anymore. Saving an extra call to GeneralUtility
to not hand this parameter over to the method in TSFE should be helpful.

However, in the future, this method will probably be changed,
the third parameter is not deprecated for now.
