9516cd9ee3 feat(library/tactic): 'exact' tactic report unsolved placeholders in nested expression 
Actually, the elaborator is the one reporting the unassigned
placeholders. The 'exact' tactic just makes the request.
To implement this feature we had to extend the elaboration interface
expected by the tactic framework.
