reads response data from persistent storage.

When there is no data in persitent store, the operation does NOT fail. In this case the
resulting promise resolves to nil instead.

@param credentials required for decryption.
@param serverOptions identifying the server.
@return {Promise<http.LoginResponse>} read from store, resolves to nil when there is no data,
gets rejected when decryption fails.

@internal Not part of public API, for library use only.
