    LBaaS V1 Log error instead of exception
    
    A test was failing because the check for pool orphans was doing a
    LOG.exception when there was no exception ever thrown during a unit
    test, so the LOG.exception call was failing.  It doesn't make sense
    for this piece of code to LOG.exception because there is no
    exception being thrown, its throwing its own exception.
