Fix beamspot tracks
The beamspot algorithm had the wrong name for the tracks, so it wasn't running. There was a warning for this:
SGInputLoader 0 0 WARNING unable to find proxy for ( 'TrackCollection' , 'StoreGateSvc+TrigFastTrackFinder_Tracks' )
but there are several warnings here, so it wasn't picked up.
This MR
- sets the TrackCollection name correctly
- makes it an error if the TrackCollection isn't found (currently a warning)
