2bc13f6bfd feat(library/tactic/exact): enforce goal type during elaboration when executing 'exact' tactic

e48df78938 feat(frontends/lean/elaborator): do not apply delayed_coercions on equation lhs 
The variables in the equation lhs do not have type at preprocessing

for delayed_coercions. If the coercions are injected, we will not be
able to pattern match. Thus, we disable coercions in this case.
