paint: Prevent crash on expanding with pattern fill 

Resolves #13501
When painting with "Expand Layers" on, we call gimp_get_fill_params ()
to get the color to fill in the new area. However, if the user has set the
fill type to Pattern, the color is NULL. This caused a crash because we
immediately try to set the alpha channel of the color to 1.0 if the layer
has no transparency - and if the color is NULL, that's not possible.
This patch checks if we received a valid GeglColor before trying to
set its alpha channel.
