Configuration changes - properly loaded when dpu template is updated?

[tomas-knap]

Please test that the following scenario works correctly:

1. Serialize configuration for DPU template A
2. Adjust the DPU configuration class for DPU template A, load it to odcs
3. Try to deserialize the previously stored configuration (with the previous version of the config class)
4. As a result, all fields except of the new one should be deserialized properly. It must not happen that default values are used for all attributes, especially those which were already saved in the previous version of the DPU template A

Motivation: Jakub reported that it behaves wrong on odcs.

Can I have more details? I have "tested" this with File Loader during the #1292 and it seems to be ok.

Jakub was testing that on metadata DPU template, which has problems with czech national chars. So it is possible that this scenario works fine. When solving issues with Czech chars, we should test this in metadata dpu template and close.
