SmsInboxAPI: print messages in opposite order

With this the newest messages appear at the bottom of the printed
list, which is the same behaviour we had before merging recent
SmsInboxAPI changes.  Finding the newest message is easier if it is at
the end of printed message, no need to scroll or at least search for
the start of the printed output.  Before this commit we had:

[
  {
    "threadid": 7,
    "type": "inbox",
    "read": true,
    "number": "+123",
    "received": "2021-04-24 20:59:16",
    "body": "bar"
  },
  {
    "threadid": 5,
    "type": "inbox",
    "read": true,
    "sender": "foo",
    "number": "+123",
    "received": "2021-04-23 13:12:28",
    "body": "bar"
  },
  {
    "threadid": 5,
    "type": "sent",
    "read": true,
    "sender": "foo",
    "number": "+123",
    "received": "2021-04-21 13:11:14",
    "body": "bar"
  }
]

With this we get:

[
  {
    "threadid": 5,
    "type": "sent",
    "read": true,
    "sender": "foo",
    "number": "+123",
    "received": "2021-04-21 13:11:14",
    "body": "bar"
  },
  {
    "threadid": 5,
    "type": "inbox",
    "read": true,
    "sender": "foo",
    "number": "+123",
    "received": "2021-04-23 13:12:28",
    "body": "bar"
  },
  {
    "threadid": 7,
    "type": "inbox",
    "read": true,
    "number": "+123",
    "received": "2021-04-24 20:59:16",
    "body": "bar"
  }
]
