[BUG] Invalid last changed information

[BUG]

How it is:
As of right now intents show Last changed: Puudub/Missing
It displays the actual last changed information(Video provided) but within a second it gets replaced.

How it should be:
When changing the content of an existing intent, it updates the last changed time.

Original Last changed issue was fixed with the new deployment.

• Fix initial loading of NLUs #657

This PR addresses an issue where upon initial load of intents NLUs under DSL/DMapper/locations/nlu - examples field was not initialised correctly and would only appear after a new intent example was added.

From now on with every deployment intents' examples should be displayed correctly after a new deployment right away on https://admin.test.buerokratt.ee/training/training/intents.

Works as intended.
