Init sync delay

Delayed the initial sync after account creation,
it's still before the wizard closes because of three reasons:
1. The sync will happen after account is saved, in contrary to how it was before
2. The only wizard step left shows something like "your email are already on their way"
3. If it were after the final step of the wizard the user would be presented with an empty screen - and now there's a good chance that the sync will end before closing the wizard
