TCP: skip_suspected_members=true prevents merge
-----------------------------------------------

                 Key: JGRP-1107
                 URL: https://jira.jboss.org/jira/browse/JGRP-1107
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.8


When we have A and B and both have TCP.skip_suspected_members set to true, then the following happens on a network partition:
- A excludes B and adds B to suspected_members. Therefore A won't send any messages to B anymore
- B does the same
- A and B would remove the sender of a message from suspected_members, but nobody will actually send any messages !
- On a merge, A and B need to talk to each other, but both will discard the message !
==> A merge will never happen

WORKAROUND: set skip_suspected_members to false

SOLUTION: before a merge, clear suspected_members (maybe handle MERGE event)
