Add KeyStore.onUserPasswordChanged for the lockscreen to call when the user changes their password. Keystore will then handle the logic of deleting keys. Instead of calling Keystore.password_uid for both unlocking and password changes the behavior has been split into Keystore.unlock and onUserPasswordChanged.
