ARTEMIS-484 Large Message Loss on Initial replication 

https://issues.apache.org/jira/browse/ARTEMIS-484

The File copy after the initial synchronization on large messages was broken.
On this commit we fix how the buffer is cleaned up before each read since
a previously unfinished body read would make the buffer dirty.

I'm keeping also lots of Traces I have added to debug this issue, so they will
be useful if anything like this happens again.
