Get RunNumber on initialize
Created by: kakwok
Currently, we get the run number from runinfo DB on starting, but we start publishing to runinfo DB after reaching configured, therefore any run that did not start will be published with a fresh SID and run number 0. These runs will sink to the bottom in the RunInfoServlet and do not appear to be recent runs. Hannes suggested we get run number on initialize to solve this problem, which is what was being done by LV0.
