feat: simplify stack info in cli error (#4749)

* fix: remove name and message from stack trace

* fix: check whether stack exist

* test: tweak test

* test: try some change

* fix: Write all output in one chunk

Apparently, the test fails randomly if the new file is written in response to a
log that is not the last one
