Registration error

[maratayzatullin]

I took clean derby-login-example application and made one successfull registration (with email). In MongoDB I had one unconfirmed 'local' account.

After that I tried to register with new email. It caused registration providerExists error: 'User is already registered with this provider'.

After successfull confirmation of first account this error disappeared.

Could you help or explain me this issue?

It's a bug. After the registration we need to flush user session.
