In expirer's unit tests, FakeInternalClient instances simulates expirer's task queue behavior. But get_account_info method of the FakeInternalClient returns container count = 1 and object count = 2, even if it simulate different count of containers or objects. This patch fixes the behavior. The return values of get_account_info will be equal to simulated container and object counts. This patch will make review for expirer's task queue upgrade patch [1] more easy.
