Add scenario in test to not settle a batch in dispute

[koekiebox]

Add a domain unit test to ensure a batch that is in DISPUTED state cannot be settled.

Scenario

1. Create transfer (which will be allocated to batch A)
2. Create a transfer under another model which will create batch B
3. Create settlement matrix A that includes batches A and B
4. Dispute batch A
5. Settle settlement matrix A
6. Test to ensure only batch B was settled and not batch A

Hi @koekiebox

1. According to the above scenario, in the requirement Number 3
   I got two batches in a Matrix, and it asked me to dispute a batch in that Matrix.
   It is not possible according to the design in Admin UI because the batches are not able to select.
   So, I want to know about the real logic that Is it possible to Dispute or Close or settle specific batch in a matrix?
   And also, there is no function to dispute Batch. I found only disputeMatrix function.

2. Is it possible to create multiple matrixes for same batches because currently we can create multiple matrixes for same batches?

1. Ok. I would work from the domain tests that reside in https://github.com/mojaloop/settlements-bc/blob/main/packages/domain-lib/test/unit/index.test.ts
   Step 3 is possible for both DYNAMIC and STATIC matrixes.
   You are only able to execute actions (close/settle/dispute) via a matrix, not through the batches directly.
   You are able to close/dispute batches (via a matrix) as long as the batch is not settled. Once a batch is settled, it is final.

There is however a new status being introduced (AWAITING_SETTLEMENT) which is currently wip.
Please have a look at the following document for background and explanation:
mojaloop/mojaloop-specification#117 (comment)

2. Yes, but only a single matrix may settle a batch. Please also read about AWAITING_SETTLEMENT
