Fix wrong card positions after card removal

After removing a card, the remembered position wasn't correct anymore.
E.g. following scenario:
- Open slim recents with two cards
- Remove the bottom one
- Long press second one to kill it
-> FC, trying to access card with index 1 -> OutOfBounds! correct would
be index 0
