test: Rework no-specs policy test

Following the previous commit, asserting on whether we are able to apply
the policy is no longer relevant. The previous commit allowed empty
policies to be applied (at the K8s apiserver level), but a parsing error
will be triggered which can be observed in the agent logs. Applying an
empty policy will not overwrite the existing policy, it'll simply
continue enforcing the previous policy. Note, the CNP on the K8s side
will be out-of-sync with the actual policy in the datapath now.
