The previous strategy for accounts management on endpoints was to send
an account creation request every time in order to retrieve the account
URL. Although it works on most cases, the contact information or key
update wasn't handled correctly.
The only drawback of this new way of managing accounts is that, if the
endpoints drops the account, ACMEd will fail to renew any certificate
for this account on this endpoint. Previously, it would have simply
created a new account. This should be fixed soon.
