ARTEMIS-3781 send PUBREC on duplicate PUBLISH for MQTT QoS 2

The MQTT 5 (and 3.1.1) specification states:

    Until it has received the corresponding PUBREL packet, the receiver
MUST acknowledge any subsequent PUBLISH packet with the same Packet
Identifier by sending a PUBREC. It MUST NOT cause duplicate messages to
be delivered to any onward recipients in this case [MQTT-4.3.3-10].

The broker prevents a duplicate message, but it doesn't respond with a
PUBREC. This commit fixes that.
