storage: TestIntegration_RequesterPaysNonOwner failed

Note: #7484 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

commit: f7ac85b
buildURL: Build Status, Sponge
status: failed

Test output

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (f7ac85b), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).
