[Metric predictor] Wrong application id on predictions

[Robert Sanfeliu]

Metric predictor is reporting app ID "anapp23" for metrics that come from another APP ID (e.g: 0930130905automated-testing-mqtt-app-1715239813411)

Below the messages sent to the message broker that demonstrate this. The first message is from EMS, with a correct APP Id, the second one is the prediction made by metric predictor.
