DRA: fix indexing of generated parameters

The claim parameter key didn't include the namespace of the claim. In the case
where two namespaces used the exact same parameter reference, the "too many
generated parameters" case got triggered incorrectly and lookup could have
returned an object from the wrong namespace.

Found while running the E2E tests in parallel:

              message: 'running PreFilter plugin "DynamicResources": multiple generated claim
                parameters for ConfigMap. dra-8794/parameters-3 found: [dra-4729/parameters-4
