lock: fix flaky TestLockFailedRefresh

Browse source 
The comparison of the current time and the last lock refresh were using
seconds represented as integers. As the test only waits for up to one
second, the associated number truncation can cause the test to take
longer than once second and thus to fail.

Switch to nanoseconds to avoid this problem. This also slightly speeds
up the test.
