Script page header URL fix

The script page heading's "script name" link (i.e. `{{{scriptPageUrl}}}`) only worked as expected on `views/pages/scriptIssueListPage.html` and `views/pages/scriptIssuePage.html`, where the partial had a context of the `script`.

I'm still working on getting a local site running, so I haven't been able to verify the fix.  Along the way I found that `console.warning`.
