Error message for HAPI-0302 shows misleading names for known resource types

[holly-smile]

Describe the bug
When a request is made for an unknown resource type, the server returns the resource types that it does know how to handle. When it does so, "List" is shown as "ListResource", which can (and already has) mislead someone trying to debug the error, especially if they then try to request a ListResource (which doesn't exist).

To Reproduce
Steps to reproduce the behavior:

1. Make a GET request to any invalid resource, like GET /Abcdefgh/1326.
2. See that "ListResource" is in the error message.

Expected behavior
The "List" resource is correctly shown as "List" in the list of resource types.

Screenshots

Environment:

• HAPI FHIR Version: 7.3.0-SNAPSHOT

Additional context
Fix is ready and incoming.

I believe that this happens specifically with "List" because List is already a type in the Java standard library, so the resource class for "List" is named differently.
