Revert line introduced in previous CL that seems to always pass `false` for `onTrustManagedChanged`

This change was introduce in commit fd27baff.
Test: verified manually,
  1. adb shell settings put global systemui/buffer/KeyguardUpdateMonitorLog DEBUG
  2. adb logcat -s "TrustRepositoryLog:*"
  3. Disable Extend Unlock and enable it, see the onTrustManagedChanged being passed with false and then true.
