Running exif_autotransform on images with orientation flag == 4 and == 2 results in an image with incorrect orientation flag #37

Code to reproduce:

image = JPEGImage(blob=jpeg_blob)
image = image.exif_autotransform()
assert image.exif_orientation = 1

The jpeg_blob should have exif orientation flag set as 4 or 2.

Expected results:
Process finishes with 0.

Actual results:
AssertionError is raised because image.exif_orientation is equal to 4 or 2.

The issue seems to be due to the fact that JPEGImage.flip() does not set exif_orientation as 1.
