GPencil: Fix unreported Fill when use boundary and Visble layers

The new option to filter the layers used by the Fill tool was not using the boundary strokes. The problem was the layers were skipped and any boundary stroke was not used.

Now, the layer is not skipped, but the strokes that are not boundary are skipped.
