Merge #6584

6584: Show ASan/UBSan logs in CI also for unit and integration tests r=def- a=Robyt3

The ASan/UBSan logs are currently only printed in the CI log when launching the client and server once.

Now the logs are also printed when the unit or integration tests fail due to a sanitizer crash.

A redundant definition of an environment variable is removed.
