not sure but this should work:
cd .node-red
npm uninstall openzwave-shared
this worked, but the whole procedure was no succes.
It still keeps re-booting over and over again when I insert a zwave node 
For tonight it's enough, if there are more ideas out there

ok, but test2.js must run without errors before you try with node-red!
One last tip, actually this should be your job 
search for the error in your log:
node: symbol lookup error: /home/pi/.node-red/node_modules/openzwave-shared/build/Release/openzwave_shared.node
Have a look here:

Ok,
christmas vacation....
Today I just re-started again from scratch.
A new Raspbian image, then I first installed node-RED with the script you can find in this forum and then I installed the open zwave library with the command that cflurin posted here above.
3 straight forward steps, and it finally works again.
Without any doubt I messed up big time by installing something wrong in the zwave part, but I was not able to find out what. At least we have now 3 straight forward steps to install this node
Thx
