    [2225_statistics_4] calculate an entire server's counts even though they are zero
    
    As well as ffd4a283b18f8eaa453712e1e615e2440b12aa0d, in the platform (FreeBSD8,
    amd64), the timer counters can be zero. However get_statistics() in counters.py
    didn't calculate an entire server's counts if they are zero. This change is
    added so that it calculates counters even though they are zero.  An new
    unittest is added to check that. This change fixes the issue reported in #2741.

    reports.
