Broken rendezvous between the Python controller and devices

[Damian-Nordic]

Problem

After merging #5938, the commissioning no longer works between the Python CHIP Controller and Nordic examples. Since Nordic examples use the common Server/RendezvousServer from src/app/server the issue may be visible on other embedded platforms, too.

@pan-apple have you tested the change with any embedded devices? Do you know what can be missing?

Proposed Solution

Find the problem, fix.

Sorry, false alarm. I must have forgotten to rebuild the firmware. Works correctly now.
