Test iprop slave ulog management

Check the ulog more thoroughly after each operation, including the
principal names we expect in each update entry.  Verify that the slave
ulog contains actual update entries received from master.  Add a
second slave which receives updates from the first.  Test a wider
variety of principal operations.  Add two additional operations after
the full resync to test that incremental updates resume after a full
resync (albeit with some lag).
