Task #33745: Integrate File Abstraction Layer
Unknown t3lib_TcaRelationService in StaticRecordCollection
t3lib_collection_StaticRecordCollection::loadContents() tries to access class t3lib_TcaRelationService which is not available in the TYPO3 Core. The accordant dependent feature request was pending for master (see #32148). Since the TcaRelationService was dropped for 4.7, this fix uses plain MM queries to get the desired results.
