[albinsuresh]

Describe the bug

The test tedge_mapper::c8y::tests::mapper_fails_during_sw_update_recovers_and_process_response is failing quite frequently on cargo test runs.

To Reproduce

Run cargo test -p tedge-mapper c8y::tests::mapper_fails_during_sw_update_recovers_and_process_response repeatedly. It fails at least once in every three attempts.

Additional Context

It was reported in the past in #570 and fixed with https://github.com/thin-edge/thin-edge.io/pull/575
