Management's 'messages matched' count incorrect for headers exchange

                 Key: QPID-1723
                 URL: https://issues.apache.org/jira/browse/QPID-1723

As reported on user list the messages routed counter for bindings from a headers exchange
is non-zero even where no messages have been enqueued:

qpid: show 8386
Object of type org.apache.qpid.broker:binding: (last sample time: 13:55:35)

    statistic  messageLatencySamples  0
    statistic  messageLatencyMin      0
    statistic  messageLatencyMax      0
    statistic  messageLatencyAverage  0

LIne 118 of HeadersExchange.cpp shows that the count is incremented regardless of the success
of match test.
