Fix drift in deleted timestamp for Notification and Database

    The deleted timestamp for the usage event and the database
    were being set at different intervals.  Now the time is
    captured once and shared between both usages.

    If the server deletion times out, a log message will be
    recorded but it will not throw an exception.  Ensures
    completion of clean up and record of deletion

Fixes: bug 1201685
