Entity list shows loading animation endlessly

[hunterckx]

For certain apps (see below), an entity list, when visited by direct URL, will endlessly show the loading animation, apparently due to the loading property of the explore state being set to true, despite the entity data being present on the client.

This has been observed to happen to catalogs using the CS_FETCH_CS_FILTERING explore mode when an authentication provider is not used; adding GoogleSignInAuthenticationProvider to _app.tsx resolves the issue (e.g. as done for BRC), and removing it from a working app (e.g. AnVIL Catalog) causes the issue to appear.
