Fix Segmentation fault when trying to print an empty plot.

Browse source 
When printing an empty plot, the function was missing nullability check for 'current_dive'. Now the print of an empty plot results with an empty blank page.
A better solution could be making unsensitive the Print entry in the menu, until a plot is loaded.
