when the extension of a target filename of a thumbnail did not refer
to a valid image format, as supported by PIL.
Instead, we want the thumbnail to be saved with whatever format the
image originally has.
The same bug also affected normal saving of a feed image (via the
``store_feed_images`` addin) under certain circumstances (when saved
through PIL), and this is tested in ``test_remote_image.py``.
