Fix AdminVersions module name

[paulomarg]

Description

Fixes #913

The admin_versions file was incorrectly set up, and ended up breaking backward compatibility by dropping the module name.

To make sure this doesn't break any existing apps, as well as to continue providing a shorthand, I aliased the values in the module to the global one as well.

Props to @scart88 for picking this up!

How has this been tested?

Via the unit tests.
