Previously to handle unevaluated objects in line art "load all"
iteration, a `include_objects` variable is added in depsgraph
iteration settings, and this was only processed by object iterator
but not for any of the dupli objects. Now `make_duplis_collection`
will also handle `include_objects`
The only case where this border case can lead to crash is that a
line art grease pencil object is inside one of the dupli collection,
which isn't a valid use in the first place. But this fix makes it
more robust.
