Add a Namespace Prefix to pageReference.state Properties and Query Parameters (Critical Update, Enforced)

Add a Namespace Prefix to Query Parameters and pageReference.state Properties was a critical update in Winter ’19 and is enforced for the Summer ’19 release. This critical update resolves naming conflicts for query parameters between package components. Starting on May 17, 2019, this update begins to auto-activate on a rolling basis. The actual date it auto-activates for your org depends on when you update to the Summer '19 release. All orgs will be updated by June 17, 2019. As with all critical updates, you can activate the update manually before Salesforce auto-activates it.
