Do not retry login after logging out

[jan-law]

The following condition shouldRetryLogin should only evaluate to true when the web-client has valid credentials and was temporarily disconnected from the backend. However, the code below evaluates to true before the user is logged in, where ready.code is undefined and ready.ready is false. hasInvalidCredentials then evaluates to false regardless of whether the CloseStatus indicated a protocol failure. shouldRetryLogin then becomes true, triggering repeated auth calls.

Login.tsx:

const hasInvalidCredentials = !!ready.code && ready.code === CloseStatus.PROTOCOL_FAILURE;
const shouldRetryLogin = (!hasInvalidCredentials && !ready.ready)
|| (!!token && ready.ready);
