Communication from Kapua to Kura broken

[tomtomh81]

Describe the bug When running a Kura device (version 5.1.1) it shows up as online within Kapua. But when trying to open one of the tabs for configuration the following error message appears:

Error There was an error while sending the request. Error: An error occurred when sending the message: org.eclipse.kapua.service.device.management.asset.message.internal.AssetRequestMessage@667ebd87

To Reproduce Steps to reproduce the behavior:

1. Have a Kura Device running, connected to Kapua
2. Open the Device tab within Kapua
3. Click for example on "configuration"-tab

Expected behavior Normally the configuration components should get loaded.

I have also running an old instance of Kapua (0.3.0) where the same Device is working properly... the configuration and the other tabs are loading like expected.
