OAuth tokens are not added to Ubuntu One after /sso-finished-so-get-tokens/

[Roman Yepishev]

STR:
  1. Make sure SSO account has one e-mail and that email was previously used in Ubuntu One.
  2. Patch ubuntu-sso-client with http->https fix for ping url - LP:627700.
  3. Run ubuntuone-preferences, it will open ubuntu-sso-client; Click on "already have the account" button.
  4. Log into SSO with your credentials, receive "Success!" message. Close the dialog. See that u1sdtool --connect makes syncdaemon go to AUTH_FAILED.
  5. Log into https://login.ubuntu.com/+applications and see that you HAVE the token there;
      Log into https://one.ubuntu.com/account/machines and see that you DON'T have the token there even though ping url returned 200 ( ~/.cache/sso/oauth-login.log)

We've cowboyed a fix for this to the edge servers and it seems to be working right.
