- Fixed bug where in the case that a pool checkout event handler is used

and the database can no longer be connected towards, that the checkout
handler failure is caught, the attempt to re-acquire the connection
also raises an exception, but the underlying connection record
is not immediately re-checked in before the exception is propagated
outwards, having the effect that the checked-out record does not close
itself until the stack trace it's associated with is garbage collected,
preventing that record from being used for a new checkout until we
leave the scope of the stack trace.   This can lead to confusion
in the specific case of when the number of current stack traces
in memory exceeds the number of connections the pool can return,
as the pool will instead begin to raise errors about no more checkouts
available, rather than attempting a connection again.   The fix
applies a checkin of the record before re-raising.
fixes #3419
