Fix loading buggy images

[wolfrosnet]

Fix an error when loading an image that had the original extension "PNG" but was saved as "JPG".
I have attached a sample image.

How about not to decide buggy images by comparing extensions and Image.mode, but using file MIME type.

For example, using get_format_mimetype method(https://pillow.readthedocs.io/en/stable/releasenotes/5.2.0.html#imagefile-get-format-mimetype)

In my opinion, using MIME type gives you much more reliable informations.
