Fix T70484: GPencil particles crash when original stroke is hidden

Due the internal design of the drawing engine and the special requirements for 2D inside 3D, it's required to keep the original stroke visible in order to display the particles. If the original stroke is hidden, the particles are hidden too.

This commit only fix the segmentation fault. Make visible the particles when the original is hidden would require a complete redesign and maybe would break some 2D features.
