MMS not being delivered when app is killed due to memory pressure

Bug 8788328

If the TransactionService is killed while downloading an mms, the
RETRIEVE_TRANSACTION can be left in a non error state in the pending_msgs
table where it won't get restarted even when the TransactionService is
restarted.
