Unit tests for APIKeyAuthentication.

Covers the access-control guarantees of the external API key authentication:
- a valid token belonging to an active user authenticates successfully
- a valid token is rejected once the underlying user account is deactivated
  (prevents an authentication bypass via a disabled account that still holds
  a previously generated API key)
