ACCUMULO-2695 Fixed Conditional writer hang caused by tablet server fault
This change fixes issues that occurred when the conditional writer got an
exception when trying to connect to a tserver. The conditonal writer could
throw an exception or loose mutations in this case. In either case the client
would hang.
