David Capello 0775b0d8ba Take care of an empty tileset in doc::Tilesets collection
We cannot delete a tileset yet from Aseprite UI, but now an extension
can do it through Sprite:deleteTileset(). Deleting the non-last
tileset will create an Tilesets array with an empty (nullptr) slot on
it (so tileset indexes are not changed, and for the future, if some
external file is referencing that tileset index, the reference will be
kept).
