Bug: restoreDevonfwIde

[denise-khuu]

There is a bug in this tutorial on katacoda.
It somehow doesn't restore the IDE or starts any setup file.

The background script does not install the devonfw-ide at the startup of the tutorial in some of the tutorials.
It seems that even the setup files for the installation are not passed into Katacoda. Normally the should be located in /root/setup (https://github.com/devonfw-tutorials/katacoda-scenarios/blob/master/devon4j-http-rest-client/index.json#L73)

Fixed for now with downgrade to an older ubuntu image #335.
Created a new task to investigate the problem #336.
