Do not request a global run number if L0 FM already did

Laurent Petre requested to merge bugfix/run-number-at-start into develop


This MR fixes a bug in the GEM FM that was systematically requesting a new run number at "Start" even if started from a L0 FM (i.e. Global or miniDAQ).

The official run number is now requested only if none if is provided in the input parameter set.

How Has This Been Tested?

In miniDAQ, the official L0 run number (as displayed in the Web interface) is now correctly propagated to the GEM supervisor and then to the managed applications. The TCDS iCI and PI show the right run number and the VFAT configuration is dumped with under the right directory.
