Fix rendezvous test failure in EventGroupsDemo (#294)

Browse source 
The rendezvous test in EventGroupsDemo assumed that one tick is not
enough for rendezvous to complete. Turns out that it is not true on a
system with 1ms tick and rendezvous does get complete within one tick.
This commit removes the test with one tick assumption.
