Telemetry fixes

[olegzil]

Description

This PR fixes Telemetry CANCEL and ARRIVAL telemetry events

Implementation

The issues had to do with job cancelation. Since the code is reactive, relies on coroutines, all long running jobs have to finish in response to a cancel or arrival event.

Testing

Pending

• I have tested locally (including SNAPSHOT upstream dependencies if needed) through testapp/demo app and run all activities to avoid regressions
• I have tested via a test drive, or a simulation/mock location app
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

Checklist

• [ x] My code follows the style guidelines of this project
• [ x] I have performed a self-review of my own code
• I have updated the CHANGELOG including this PR
