Merge "getTokenToEndpointMap should be sorted by the API" from Amnon 

"This series change getTokenToEndpointMap implementation, so that the result
 will be sorted by the API.

 The API returns the tokens sorted according to their type. The APIClient helper
 method was change to keep the original order and getTokenToEndpointMap was
 change so it will return the map as is, without re-sorting it."
