Fixes #90
The original HZ member uuid is saved as a cluster member attribute.
Consequently, even if HZ changes it during partition merging, HAManager and ClusteredEventBus will keep using the same original uuid.
Note that when member added event is handled by existing cluster nodes, the member attribute may not be saved yet.
In this case, it is safe to use member uuid (at this stage, the member uuid and member attribute are equal).
