[FIX] web: conflict in qunit type definition

In the QUnit type definitions, there is a QUnit namespace and a QUnit
interface. When using a jetbrains IDE, it is confused between the two
and thinks the global QUnit is the namespace.
This means that it can't resolve QUnit.test, QUnit.module, etc

This fixes this issue by disambiguating between the two.
