Fixed flakiness in GetMostRecentlyAddedUserNodeForURLSkipsManagedNodes.

Fixed flakiness in GetMostRecentlyAddedUserNodeForURLSkipsManagedNodes.

base::Time::Now() doesn't guarantee that successive calls don't get the
same value, and this seems to be happening on some Windows systems when
two BookmarkNodes are created one after the other in a unit test.

Thanks for the heads up about this test.

The test error log and the documentation of base::Time::Now() made the problem
obvious :-)

PTAL, thanks!
