transaction: leave unfinished without crashing when not properly released

I think the transaction.__del__ is there just as a last resort in case
we (or an extension) forgot to release the transaction. When that
happens, the repo can (or will on Python 3?) get deleted before the
transaction. This leads to a crash in test-devel-warnings.t on Python
3 because we tried to access repo.dirstate, where repo was retried
from a weak reference. There's not much we can do here, but let's at
least avoid the crash. The user will have run `hg recover` afterwards
regardless.
