Ensure weakref finalize_fairy operates upon the current connection
Fixed a fairly serious connection pool bug where a connection that is
acquired after being refreshed as a result of a user-defined
:class:`.DisconnectionError` or due to the 1.2-released "pre_ping" feature
would not be correctly reset if the connection were returned to the pool by
weakref cleanup (e.g. the front-facing object is garbage collected); the
weakref would still refer to the previously invalidated DBAPI connection
which would have the reset operation erroneously called upon it instead.
This would lead to stack traces in the logs and a connection being checked
into the pool without being reset, which can cause locking issues.
