Wrong offline mode behavior #367
Description
After a rigorous testing of the authentication sequence interrupted by entering offline mode, I have found an incorrect behavior of MAS v.2.1.00 in part of the exception handling logic. I see the root cause to be an incorrect authentication process behavior when an OAuth request cannot be performed due to offline mode. There is a missing exception handling thrown by OAuthClient in MSSOService class (https://github.com/CAAPIM/Android-MAS-SDK/blob/Stable/mas-foundation/src/main/java/com/ca/mas/core/service/MssoService.java#L198).
As far as I can see, the handleErrorResponse() call shall be added to the catch block (OAuthException and OAuthServerException) in order to notify listeners on the failed authentication process (via the MASCallback.onError()).
