* We waited to clear the incomplete flag until security was agreed
to, but this can lead to accounts left incomplete; we now clear
the flag as soon as the AccountManager account is created (by
convention, this is when the EmailProvider account is complete)
* Also, allow onDone() to be called more than once with a saved
account, leaving cleanly, rather than throwing a runtime
exception
