core: always create a fake profile if there are no samples

Browse source 
Before making the cylinder-table dynamic, dives always
had at least one cylinger. When such a dive is displayed,
the TabDiveInformation class calls per_cylinder_mean_depth().
If there are no samples, this function generates a "fake
profile" with fake_dc(). Thus, effectively dives always
had samples once the user was displaying them.

When the cylinder-table was made dynamic, dives without
cylinders were supported. This can notably happen, when
importing from CSV (this could actually be a bug).
per_cylinder_mean_depth() exits early in that case and
doesn't create a fake profile. This lead to crashes
of the profile-widget, which were fixed in 6b2e56e513.
Non-sample dives were now shown with the Subsurface-logo.

To restore the previous behavior, genarate a fake profile
for sample-less dives in fixup_dive(), which is called
anytime  a dive is loaded or imported. This seems to
have been the intention anyway and this worked only
"by chance". This will make a few fake_dc() calls obsolete,
but so be it.

Since fake profiles are now generated on loading,
the parse-tests need to be fixed to account for that.
