fix: build error caused by removed py2neo package
Deployments are failing now because the py2neo
PyPi package has been deleted by its owner. In this MR I'm cherry-picking this fix. We could have avoided this and just upgrade Tutor to 14.2.5
as described in this post, but this version still doesn't have a fix for another issue that our fork contains.
Original message:
On Oct. 10, py2neo package was abruptly removed from pypi, GitHub, and
the py2neo website now displays just a super funny meme: https://py2neo.org/
Yes, we should get rid of that dependency, but we are still supposed to
support existing users. So we install py2neo from our fork.
