[FIX] payment: py3 error payment icon save

Code to thumbnail payment icon image had an error for python3 because
from RPC the image would be a text string instead of an expected
bytestring.

This change accepts both and made another small fix in the view since
image_medium doesn't exist (and image is already thumbnailed).

A third fix was that removing an image caused an error.
