Fix rendering bs requests with bootstrap UI (in production)

When in production mode we don't have the font-awesome stylesheets and
helper methods, eg. `icon()`. Since the rendering of bs requests via
ajax was not done with the `switch_to_webui2` switch this was causing
a bug which was only visible with using only compiled assets.

Fixes #5756
