Explicitly list widget JS in FooChooserAdapter media

This is necessary (according to the logic for adding Django form media objects together) whenever the JS adapter definition depends on anything defined in the widget JS - e.g. if foo-chooser.js defines `window.FooChooser`, and foo-chooser-telepath.js references that in the definition of FooChooserAdapter, then the only way to guarantee the correct ordering is with an explicit `['foo-chooser.js', 'foo-chooser-telepath.js']` media definition - adding two media objects does not guarantee this ordering.
