Title: Bubble db not found errors

When requesting the _changes feed of a deleted database with a continuous
or longpoll style we would return a `400 Bad Request` error instead of
the correct `404 Not Found`. This was because we were swallowing all
errors when validating the `since` parameter. This patch just catches
the except and returns it appropriately.
