[skip-changelog] Fix integration test intermittent failure due to download/file in use (#1905)

* Do not run go integration tests in parallel

This is required since the integration tests shares the download folder.
Still not ideal, it would be better if the cli could handle concurrent
access to the download folder (from multiple cli processes...), but at
least allows to run the tests without random failures.

* Fixed integration test
