Summary0048847: JIRA 2948: SynchronizationBuffer loads messages in a random order
DescriptionWhen adding more than one message into Messages state model inside the same state action, sometimes the import entry for the second added message is created before the import entry of the first added message.

The problem seems to be that the "time" property of the messages is being considered to sort them, and the time of the OBPOS_Order message is the same one as the time of the messages generated on the backend (see attached screenshot), and as a consequence their order will not be deterministic.
Steps To ReproduceAdd following postHook to completeTicket action:
OB.App.StateAPI.Global.completeTicket.addPostHook(globalState => ({
  ...globalState,
  Messages: [
    ...globalState.Messages,
    OB.App.State.Messages.Utils.createNewMessage(
      'MyModel',
      'MyModelEndpoint',
      {}
    )
  ]
}));

Add log into findAll function in MessageModelController.js and check sometimes OBPOS_Order message is retrieved first (the one added inside the state action) and other times MyModel message is retrieved first (the one added inside the post hook).
The same happens in ImportEntryBuilder.createImportEntry.

Fixes ISSUE-48847: Guarantees proper message processing order

The problem was that if some messages for the same backend are created within the same millisecond, they will have the same
value in their time property. If two messages have the same time, then when the MessageModelController retrieves them from
the database [1], there will be no guarantee that they are returned in the same order they were added to the messages queue.

To fix it, now the MessageModelController will add a sequence number (its position in the incoming message list) to each message
before storing it in the database. It then uses both the time property and the new sequence number to read the ordered message
list from the database.

Also when setting the time of the message, new Date().getTime() has been replaced with Date.now() because it has better performance.
