[Bug] node 'ioBroker get' crashes node-red with js-controller >= 5.0.14

[TheRealArthurDent]

When using the node 'ioBroker get' to fetch a non-existing value causes a fatal crash of node-red when using a js-controller >= 5.0.14. Most likely this is caused by this change in the js-controller.

For a detailed description, please refer to the respective issue raised at js-controller inluding a suggestion on how to fix the issue.

I finally found the time to try the fix suggested in the forementioned issue. Kudos to @foxriver76, the fix in fact does the trick.

@Apollon77 I've noticed that you released 5.0.0 recently. Shall I create a PR for the fix based on 4.0.3 (a.k.a. are you planning to release a bugfix version 4.0.4) or should I just create a PR to master?

PR to master please ... when it will be e 5.0.1
