add fallback for old mutable format

Fixed regression caused by :ticket:`8133` where the pickle format for
mutable attributes was changed, without a fallback to recognize the old
format, causing in-place upgrades of SQLAlchemy to no longer be able to
read pickled data from previous versions. A check plus a fallback for the
old format is now in place.

Fixes: #8133
