Empty export

See merge request !415

It could happen that PeTrack deleted all trajectories on loading a new project,
because it thought the intrinsic calibration changed. Whether that happened or not
depended on the exact options in the .pet file. 
Fixed by accepting the loaded calibration as not new, no matter what the options are.

When the PR is closed and not merged, the MR gets also closed. When it
