The common db replicator's code path for reclaiming deleted db's beyond the reclaim age was not covered by unittests, and a AttributeError snuck in. In writing the test that would cover the common code both for accounts and containers I discovered another KeyError with the container conditional for validating the container's fully reported status. This fixes both those issues and adds additional tests for the cleanup empty account container partition and suffix directories. Change-Id: I2a1bfaefebd05b01231bf71dd908fcc49adb4c36
