Document finalizeMessageExecution.

Cause partial execution failure to abort transaction.
When some messages succeeded and some failed, make successful messages available for immediate processing, and make failed messages go through usual conditions (involves postponing them).
This fixes a stupid mistake in makeMessageListAvailable invoquation on delay_uid_list instead of [uid] in finalizeMessageExecution..
