GPencil: Fix unreported random rotation for single point with texture
When using ``Path`` alignment, if the stroke has one point the texture rotates
randomly when move the viewport. This was because with one point is impossible
to calculate a path.
Now, if the stroke has only one point, the texture for this stroke is aligned
to Object.
