Description

Follow up to needed for arrow/pull/3693/files.

appveyor-cpp-build-mingw.bat has not yet enabled Python tests, need to revert,

-DARROW_PYTHON=OFF

Suggestion was to use,

diff --git a/ci/appveyor-cpp-build-mingw.bat b/ci/appveyor-cpp-build-mingw.bat
index 06e8b7f7..3a853031 100644

However, this suggestion currently trigger a built error in Travis,

Therefore, additional investigation is needed.
