Fix laggy minimized card moving

CardWindowManager created and destroyed QPropertyAnimations for card
sizes and positions on every single touch update, which caused considerable
lag while moving the cards. Fixed by removing the animations and setting
the sizes and positions directly.

Fixes GF-1334.
