Calling Feature.enabled? with wrong arguments should raise error in tests

Follow-up to https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/14429#note_191701808

Calling Feature.enabled? with wrong arguments (eg. default_value instead of default_enabled) raises an error

> ::Feature.enabled?(:foo, project, default_value: true)
ArgumentError: unknown keyword: default_value

However, no error is raised in tests because spec_helper has allow(Feature).to receive(:enabled?) { true }.
