Description

This PR fixes redirect bug with the Community Connect logo -> 'continue' button. It now properly redirects to the correct city, and resets the redux state correctly without needing to force a page refresh.

• Changes the 'continue' button to a router link button
• Adds a clearSavedResources redux action and reducer to clear saved resources without needing a refresh when the continue button is refreshed

Fixes #369
