Incorrect PDF export if stroke-dasharray has 0
#### Summary:
Objects with `stroke-dasharray` having zero in it (e.g. `0 1`) are not shown on PDF exports.
#### Steps to reproduce:
- open Inkscape.
- draw a rectangle with fill and stroke
- set a custom dash pattern to `0 1`
- export to PDF
#### What happened?
The rectangle is invisible.
The fill of the rectangle should be visible even if the stroke is not due to the dash pattern.
