Caused by rBf83aa830cd00.

Since above commit, only meshes in editmode were considered for drawing
(because
BKE_view_layer_array_from_objects_in_edit_mode_unique_data_with_uvs was
used), but the option needs to work for texture paint mode as well, so
use BKE_view_layer_array_from_objects_in_mode_unique_data instead on
pass the draw_ctx->object_mode.

note: there is no good filter_fn to check if we have UVs if mesh is not
in editmode, this shouldnt cause much of a performance hit though.
