Fixes the client-side tests after the removal of the <base/> tag from
the main layout.
These fixes aren't ideal. At the moment, they will suffice. This comment
(https://github.com/angular-ui/ui-router/issues/212#issuecomment-60803437),
among others in that issue, led me to choose this method as the fix to
avoid having to change any other core code.
* fix(articles): Article controllers name conflicts
Fixes the naming conflicts for the Articles controllers.
Due to how Angular injects the controllers into the StateProvider,
naming conflicts were caused between the Articles public & admin module
controllers.
To resolve the issue the referenced controllers in the Articles admin
route configurations must be unique, and match up with the Admin
controllers.
* Client-side tests failing
Fixed the client-side tests that were failing due to the naming
conflicts.
This feature introduces a breaking change, that restricts the User's that
can create/edit/delete Articles to only those that have the `admin` Role.
Fixed ESLint issues.
Resolved merge conflicts, and moved new client Article Service
`createOrUpdate` functionality to new Admin feature controller.
Removed edit functionality from client-side Article controller.
