Issue:
templates with (inline) template strings breaks bundling of SSR pages
## Summary
Noticed that when bundling an SSR page that itself happened to contain template literal strings, Rollup was breaking.

For example
```sh
src/
  pages/
    posts.js
  template/
    app.html
```

And then _app.html_ might look something like this
```html
<!DOCTYPE html>
<html lang="en" prefix="og:http://ogp.me/ns#">
  <head>
    <title>Some  Title</title>
    <script>
      const message = `The current time is ${new Date().getTime()}`;

      alert(message);
    </script>
  </head>
  <body>
    <page-outlet></page-outlet>
  </body>
</html>
```

Will result in a parse error from Rollup
```

## Details
You'll notice that the parse error happens on a line where a the ` from _app.html_ starts.  This is likely an escaping issue with how we are ["packing" static templates into SSR pages at build time](https://github.com/ProjectEvergreen/greenwood/blob/v0.29.0-alpha.4/packages/cli/src/lifecycles/bundle.js#L215).
