Revision 1712291

SLING-5243 : make tests more resilient by better handling incomplete votings (that should not occur in real-life though): View.matches/matchesLiveView now throw an Exception when they notice an incomplete structure - such as no members resource - and the callers of these methods properly react: analyzeVotings skips such a voting and the heartbeatHandler switches to TOPOLOGY_CHANGING in this case, but without starting a new vote
