Blender Version
Broken: (example: 2.8 2018-11-28 6fd5f95call)
Worked: (optional)

Short description of error
Convert button in particle systems with objects for hairs does nothing (couldn't find any report on it yet, sorry if duplicate)

Exact steps for others to reproduce the error
Add cube as emitter, add particle system to it and set it to hair, make it render objects as strands. Click convert on the particle modifier or use "Make duplicates real" operator.

Looks like a problem with base->object->transflag

On file load this gets set once in BKE_object_handle_data_update()

ob->transflag |= OB_DUPLIPARTS;

in get_dupli_generator() (for info stats)

ob->transflag is still 2048

But then in object_duplicates_make_real_exec():

if I check CTX_data_active_object(C)->transflag it is 0
thus in selected_editable_bases iterator: base->object->transflag is 0

Thus it earlies out in make_object_duplilist_real():

if (!(base->object->transflag & OB_DUPLI)) {
	return;
}

@Sergey: could you check on this?
