storage/indexeddb/modern/transaction-scheduler-3-private.html is a flaky timeout.

Dashboard shows that it's timing out on Sierra Debug WK2 intermittently only.
Usually the test passes in about a second but when it times out, the test runs for 125 seconds 
the first timeout on the dashboard is 5/10/2017 but this does not appear to be the first time the test has timed out.
