[Python] Dataset expression != returns bool instead of expression for invalid value

Details

    Description

      It's a bit a strange case, but eg when doing != {3} you get a boolean result instead of an expression:

      In [8]: ds.field('col') != 3                                                                                                                                                                                       
      Out[8]: <pyarrow.dataset.ComparisonExpression (col != 3:int64)>
      
      In [9]: ds.field('col') != {3}                                                                                                                                                                                     
      Out[9]: True
