The test started failing after 6dec85b19d because
a single call to a gc HTTP endpoint was prepended with a compaction endpoint.
The former does create a task which detachment waits for, the latter does not.

This test does not seem to care about gc outcome at all, so removing compaction
seems safe. The underlying issue is still there: the compaction HTTP endpoint
can race with tenant detachment. We only use the endpoint in testing, so it may
be worth checking other tests altered in the aforementioned commit.
