Feature Request: Attempt to route users to their destination at login

[froboy]

Current behavior:
When users attempt to use a link that's not the VY homepage they are presented with a login and then redirected back to the homepage.

To recreate:

• In a new session, visit https://sandbox-carnation-std-virtual-y.openy.org/virtual-ymca#/categories
• Click "Enter Virtual Y"
• Observe you're taken to https://sandbox-carnation-std-virtual-y.openy.org/virtual-ymca#/ instead of /categories

Desired behavior:
When a user attempts to visit a page we should keep track of the request and attempt to redirect the user back there upon login. If the user is not authorized to see the destination page, the appropriate error should be thrown with a suggestion to go back to the VY homepage.

• User attempts to visit https://virtual-y-demo.y.org/virtual-ymca#/categories/video
• User is presented with VY Login
• After successful auth, user is redirected to https://virtual-y-demo.y.org/virtual-ymca#/categories/video
