Ghost/core/server/helpers/meta_description.js
Markus Siemens c5fe9aa99f Rewrite meta_description and meta_title to depend upon the current context
closes #4850

- fixed `meta_description` and `meta_title` when used within a `{{#foreach}}`
- `meta_description` and `meta_title` now depend upon the current context
  to get the right string (author bio, tag description, ...).
  Note: `ghost_head.js` and `ghost_head_spec.js` have been touched to add
  the required context information when calling the helpers.
