Refactored luaevent.lua (unlearned borked fairness, collapsing useless code).

luaevent.lua:
 * Unlearned fairness since it was likely to be broken...
   fairness will need to be implemented at app-level where it should be.
 * Collapsed duplicate code into a local function
testClient.lua:
 * Added a completion message (since the test was so quick I thought it was broken)
