Increase period of ticks in start-stop memory scheduler test

This test is flaky on Fuschia due to a timeout whose root cause
is 6 ticks for the LIGHT detail invocations when less than 5 are
expected.

We believe that this is because the Fuschia scheduler is not
scheduling the test thread for more than 1ms which allows the BG
thread to get two ticks in. This causes the count to be greater
than expected.

By increasing the time between ticks, we should make it significantly
more unlikely that a test will fail in this way. This slightly
increases the time taken to test from 10 to 30ms but most other
fixes would significantly increase the complexity of the code to
remove the race entirely
