UI: Inconsistent menu item ordering

Logged out: When on VP's [blog](https://blog.vaultpress.com/) or [help](https://help.vaultpress.com/) pages, the order of the "Help" and "Blog" menu items is switched compared to the rest of the site. [Example](https://vaultpress.com/features/).

Screenshots:

Start by locating how the logged-out menu is rendered on the blog and help pages, then compare its Help and Blog ordering with the features page shown in the issue. Confirm the corrected order on all three page types while logged out.
