onTrustChanged callback triggered before onTrustGrantedForCurrentUser

KeyguardStateControllerImpl updates its internal state onTrustChanged,
which is then used onTrustGrantedForUser when the keyguard may be
dismissed, so the #onTrustChanged callback needs to be called
first, or else we may mistakenly end up preventing a keyguard
dismissal: "KeyguardSecurityView: Tried to dismiss keyguard when lockscreen is not dismissible and user was not authenticated with a primary security method (pin/password/pattern)."
