is this a leftover from creating the test? should we remove it here since it's not asserting and the other test is actually asserting

Bug: Commented-out debug code leftover from testing

The commented-out SENTRY_AUTO_INIT environment variable appears to be a leftover from development. The diff shows it was changed from "false" to "true" while remaining commented out, indicating this was part of local testing and wasn't meant to be committed. As the PR reviewer noted, this line doesn't contribute anything to the test and could be removed.
