Corrects a (very) longstanding bug of tactics. As is were, tactic expecting
constr as argument (rather than openconstr) assumed that the evar_map
output by pretyping was irrelevant as the final constr didn't have any evars.
However, if said constr was defined using pre-existing evars from the
context, the evars may be instantiated by pretyping, hence dropping the
output evar_map led to inconsistent proof terms.
This fixes bug #2739 ( https://coq.inria.fr/bugs/show_bug.cgi?id=2739 ).
Thanks Arthur for noticing it.
Note: change still has the bug, because more serious issues interfered with
my fix.
