Updates to tests reflecting the diangostic changes in previous commit. It is worth pointing out that the reason that so few diagnostics are effected is because of the filter I put in where it only goes down the new path if the borrowed place is not a prefix of the dropped place. (Without that filter, a lot of the tests would need this change, and it would probably be a net loss for the UX, since you'd see it even in cases like borrows of generic types where there is no explicit mention of `Drop`.) 2018-09-17 23:52:31 +00:00			`error[E0713]: borrow may still be in use when destructor runs`
