    LUCENE-9935: Clone term vectors reader for merges (#182)
    
    The newly added assertion in the bulk-merge logic doesn't always hold
    because we do not create a new instance of
    Lucene90CompressingTermVectorsReader for merges and that reader can be
    accessed in tests (as long as it happens on the same thread).
    
    This change clones a new term vectors reader for merges.
