=per #15590 Increase efforts to in-order on start of ALOD

AtLeastOnceDelivery can delivery out-of-order, and that's OK.
Although, in the case of message replay followed by taking user land
commands which may trigger `deliver` calls, it is nicer to at least once
try to send the replayed but not confirmed deliveries *first*, before
sending the completely new deliveries.

This change acomplishes this by triggering redelivery explicitly when
recovery has finished, and setting the timestamps on these messages a
bit in the past, so they hit their redelivery deadline right away during
this recovery induced redelivery.

* scala-library.jar had changed name to scala-library-2.10.4.jar
* use wildcard to avoid same problem when scala-library version is changed
