Pin signin/unlock UI inconsistent (4 attempts for signin, 5+1 for lock)

Project Member Reported by allenwebb@google.com, Jan 9

Issue description

Chrome Version: 73 (may affect previous versions)

What steps will reproduce the problem?
(1) Setup a pin on an account
(2) Lock the screen
(3) Make 5 incorrect attempts
(4) Enter the correct PIN

What is the expected result?
The UI should allow exactly the number of attempts allowed by the hardware.

What happens instead?
The 6th attempt fails even if correct because the hardware only allows 5 attempts.


What steps will reproduce the problem?
(1) Setup a pin on an account
(2) Reboot
(3) Make 4 incorrect attempts

What is the expected result?
The number of sign in attempts allowed should match the number of unlock attempts allowed.

What happens instead?
The 4th incorrect attempt falls back to the password (instead of the 5th).

I suspect that we're checking if PIN is still enabled before we submit the PIN authentication attempt; we should check if PIN is enabled after the auth attempt completes.
