Catch invalid roomID

[kolbymckeown]

Describe the bug
When a user navigates to a URL with an invalid / nonexistant roomID ( /room/voting-room/{id-doesnt-exist} ) the "Waiting for data..." appears instead of a page saying the roomID is invalid

To Reproduce
Steps to reproduce the behavior:

1. Navigate to URL: http://localhost:3000/room/voting-room/{some-id-that-doesn't-exist}
2. Observe the page "Waiting for data..."

Expected behavior
A page / modal should appear displaying "Invalid Room Id", that has an input to type in the valid Room Id, and on Submit would redirect user to the /room/voting-room/{roomID}
