If the remote node shuts down during the AAE compare phase an unhandled
exception (shutdown/timeouts/...) from a gen_server:call to the remote

This commit attempts to handle this in that we catch any exceptions
thrown during the compare call in plumtree_metadata_hashtree and
return an error to the caller instead of crashing.
