Makes sure that the CS_NEED_TO_VERIFY status is carried forward
and sets the showPin flag that triggers the 2 different states
in de QML UI.
The new credential UI will have one page for username/passwd,
used for setting up an account or switchting to a different
account, and a second page to enter a PIN only.
