expand recipes and roles for non-partial search

[anatolijd]

Recipes and Roles result is different for partial and non-partial search.

Partial search does expand node nested roles and all their run-lists. Non-partial search returns just recipes and roles listed in node run_list only.

Both search methods should return the same results.
