Currently, test components use their applicationId to namespace their R class.

See Issue 162244493.

In 7.0, we're introducing namespace and testNamespace DSL elements (see Issue 172361895). If a user specifies either of these, we'll use testNamespace or namespace + ".test" to namespace the test component R class. Otherwise, we'll continue using the applicationId, but that behavior should eventually be deprecated.
