When enabling the dynamic demo plugin in the e2e tests, the condition we use to confirm that it was successfully enabled is the existence of the new nav item. In the crontab plugin, we check the plugin status table for a "Loaded" status. Since the crontab plugin method is more reusable, we should update the dynamic demo plugin test case to match it for consistency.

AC: In the e2e dynamic demo plugin should be checking for the plugin's status on the ConsolePlugin list page, after it gets enabled.
