    Fix improper error message when reducing partition size

    When attempting to reduce partition size from the GUI, a generic
    error message is returned. This occurs because providing the complete
    error details to the error handler can lead to the generation of
    a distinct exception.

    Test plan:
      Install Standard. Create partition and
      attempt to reduce size from GUI.
      Verify that error message indicates
      that is not possible to reduce partitions.
      Also verify that right error message is present in
      horizon.log and that any other exception dissapear
      for this action.
