    [Flaky-test]: Fix MLTransactionMetadataStoreTest.testInitTransactionReader 
fails sporadically (#14532)
    
    ### Motivation
    
    #14525
    
    When update states is `TxnStatus.COMMITTED`,  Not correctly 
`completableFuture.complete`.
    
    ### Modifications
    - When update states is `TxnStatus.COMMITTED`, Add return to ending. Avoid 
direct calls `completableFuture.complete` from other logic.
    
    ### Documentation
    - [x ] `no-need-doc`
    
    (cherry picked from commit c15d0ef24e37df6b86bc8f4c27d43af27f8cc663)
