Revision 1712651

SLING-5243 : reverting previous commit rev r1712584 plus also moving retrieving of the establishedView back to where it was prior to SLING-5195 (rev 1711257) : reason is that SLING-5195 introduced a regression which resulted in the rather ugly retry-loop introduced in r1712584. Now reverting that retry-loop and actually fixing the regression of rev1711257 by retrieving the establishedView *after* checking for ongoing votes - cos otherwise a nasty race condition can show up
