404 Not Found Whitelabel Error Page

[kaladay]

When the API path is incorrect, a 404 Whitelabel Error page still happens.

It would be great if we could get a more normal 404 error page by handling this particular instance, such as: http://localhost:9000/patron/1234/holdss.
With that extra s we should be getting a simple 404 not found, such as:
http://localhost:9000/patron/1234/holds
