Always make sure the planner starts with at least one cylinder

Browse source 
void DivePlannerPointsModel::setupCylinders() in diveplannermodel.cpp
handles setting up cylinders for the planner. If there is a current
dive, cylinders form that dive are copied. Otherwise the default
cylinder is added and lacking that a standard size cylinder.

If the current dive does not have any cylinders, we could end up
without cylinders. This patch adds a test for this case and delegates
to the other two sources of a cylinder in that case.
