Fix track observer tool segfault
The track observer tool was causing a segfault due to missing perigee parameters on tracks that were not yet fit. This MR ensures all ObservedTracks have a perigee by fitting them as soon as they are saved to the ObservedTracks map. This will slow down running, but since the track observer tool is not used in the default reconstruction this should not be an issue. Also removing a few stray printouts.
