Comment (by codezen8):

 @westonruter I restored two of the sites from backup to version 4.7.5,
 updated the sites to 4.8.1 and applied the patch. The widget admin screen
 loads fine after the patch and the widgets work as expected.

 The admin screen not loading pre-patch must have something to do with the
 fact that PHP (7.0.19) is set up as a development server for those sites,
 because I did not get the same error on admin page load for a warning on
 the same version of the production sites when we updated them (also
 running 7.0.19 but in production mode).
