I ran across two similar problems with the /write_node()/ function in
the py2neo code. The problem seems to be that the code makes too many
assumptions about the node its been given to format.
I made an issue for it here:
https://github.com/nigelsmall/py2neo/issues/434
and a pull request for the patch I created here:
https://github.com/nigelsmall/py2neo/pull/433
My code creates nodes using the legacy.batch() code.
