ParseFacebookUtils.isLinked is returning true after that link process has failed

[ClarkXP]

The case is the following:

• I have an facebook (a@some.com) account linked in Parse.
• With other account (logged with email, b@some.com) I try to link with the first account.
• isLinked method return false before to try the link proccess.
• Parse return the error: "this auth is already used"
• isLinked method now return true, although the process has failed
• In Parse-server the authData field never is touched (User model)

To restore the correct status of the email account, I have to log out and log in again.
