No script error page has inaccurate instructions

On the noscript error page, users are requested to enable javascript in their browser and refresh the page. Refreshing the page however simply reloads the error page.

The page probably needs a script tag which brings the user to the homepage or /me when the error page is loaded.

I don't think this message needs to be in a span. In order to be consistent with the markup of the other pages, it's probably sufficient to just put in a `p` tag. This should remove some of the extra code that has been added in this PR. Looking at it, it wasn't necessary for the text in the `noscript` page to be italic anyway.

I'm personally also not a big fan of using generic elements in CSS selectors, so would be in favor of updating the span rule to something like `error-instruction`
