Fixed editor crash using cylinder shape component (#5037)

Browse Source 
Fixed cylinder shape by considering shape config list to be empty.

The crash came from clearing shape config list when cylinder height is zero, but when the height is restored to zero it was expecting an element in the list.

The code to set the shape configuration was the same for many shape types, so it has been refactored to a helper function.

Fixes #4999
