Bug 42133: Restore plugins when editing items in batch

It has been broken then fixed then broken again, several times...

This patch fixes 2 problems:
1. The CSRF fix (I think it's coming from there) didn't adjust the 'if show' test and the JS code from plugins was not injected into the template
2. The selector to call the plugin didn't include this view, only the
   add/edit items

Test plan:
Confirm that you can now use cataloging plugins when editing items in
batch
