Greeter design - weird passcode input colors

[c4pp4]

Release: dev OTA-21 with applied #401

Steps to reproduce

Expected behavior

When entering passcode, each circle is filled with white color.

Actual behavior

When entering passcode, each circle is filled with white color except the last one. When the last number is entered, it looks like this:

The last correct digit should fill the last circle and than (after half second) should give access to the phone's desktop.

Filling the last circle is alright, but let's not delay the unlock action just to see it a bit longer please.
