fix(logging): relax ThrottledAnalytics two-session test (#1667)

Because file system operations are not guaranteed to complete in the
order in which they were started, this test was previously flaky.

It seems in line with the goals of the test to just allow either
session to “win” the lock file, so do that instead.
