update content hashes of generated chunks

FIX: FileProcessing Unit Tests

Because the ChunkGenerator implementation and behaviour changed in the previous pull request, we need to adapt the FileProcessing unit tests that build on top of it. Namely it generates different chunks now and we needed to update the expected content hashes lists.

Additionally this fixes a misconfiguration of the FileProcessor template, causing a too coarse-grained file chunking.
