[FIX] Payment: prevent error in rendering payment icon list with PIL …

…incompatible icon image formats

Replace the use of 't-esc' with 't-field' for the payment icon image in
the icons list template. The latter, for an image field, provides two
options for rendering the payment icon image: use the PIL library to
obtain the image when given the option 'qweb_img_raw_data', or use a
URL. The former only considers the first option, allowing only image
formats compatible with the PIL library.
