t3lib_beFunc::thumbCode doesn't respect "file_refernce" types
The upload folder detection in t3lib_befunc::thumbCode doesn't check the "internal_type" => "file_refernce" setting and might prefix the filepath by accident.
[BUGFIX] Handle file_references properly in t3lib_befunc::thumbCode
Group fields with internal_type "file_reference" reference the files
directly. The filepaths don't need any additional uploadFolder prefixes.
Due to the FAL changes in that method, this patch is not relevant for 6.0.
