Binarization creates 2 source files in target workspace

[VolkerHartmann]

While binarizing image to a new workspace two tifs will be created.
The filename of the image is not the filename of the given mets.xml!
It seems the filename of the METS file in the cache directory!?

(source) Files are stored in the root directory of the workspace and looks like this:
file.path.to.old.workspace.filename
and
file.path.to.new.workspace.file.path.to.old.workspace.filename

The original file (OCR-D-IMG/filename) is missing in the new workspace!
(Inside METS is a reference to the first file mentioned above!)
Steps:

ocrd workspace validate
ocrd workspace clone -a -m mets.xml
cd /tmp/pyocrd-'xyz'
ocrd-kraken-binarize -w /new/target/dir

These dot-separated files are the names come from the URL of the thing, e.g. file:///path/to/old/workspace/filename --> file.path.to.old.workspace.filename.

Nonetheless, things go wrong, need to debug this with a METS URL.
