[portal] UI not working properly if devMode is enabled

[marcusschroeder]

Summary

When devMode is enabled the portal does not work as expected and throws the following error:

Chrome:
Transition Rejection($id: 0 type: 6, message: The transition errored, detail: TypeError: Cannot read property 'devMode' of undefined)

Safari:
Transition Rejection($id: 0 type: 6, message: The transition errored, detail: TypeError: undefined is not an object (evaluating 'toState.data.devMode'))

Current Behavior

I am unable to navigate properly, e.g. Logs, My Account, Documentation etc. is not accessible and thus I can't make changes to the API Gateway.

Expected Behavior

Portal is working normally, even if devMode is set to true.

Steps to Reproduce (for bugs)

1. check out "gravitee-management-webui" and follow the install instructions
2. set devMode: true in constants.json
3. yarn run serve
4. open browser and navigate through portal
