OnDeactivate

Defines route lifecycle method routerOnDeactivate, which is called by the router before destroying a component as part of a route change.

The routerOnDeactivate hook is called with two ComponentInstructions as parameters, the first representing the current route being navigated to, and the second parameter representing the previous route.

If routerOnDeactivate returns a promise, the route change will wait until the promise settles.
