Presence data is overwritten on reconnection

[davyskiba]

When updating presence data in response to connection state change, PRESENCE_ENTER message is sent with an updated data and followed by UPDATE message with previous value.

This issue was found when working on AAT Subscriber faultWhilstTracking NetworkConnectivityTest for TcpConnectionUnresponsive fault, implemented with this PR. To observe the issue remove the delay in ChangeResolutionWorker. Internal slack discussion can be found in this thread.
