Desktop: support no-cylinders in dive information tab

The tab was crashing if there were no cylinders because
1) per_cylinder_mean_depth() would access non-existing cylinders.
2) TabDiveInformation::updateProfile() would access a non-existing
   mean.

Fix both of these crash conditions by checking whether the dive
actually has cylinders.
