1850: Fix multi card activation

[f1sh1918]

Short description

This pr fixes the issue that the same card could be activated twice on the same device, even the first card is changing to an invalid state. Basically if the same card is already activated on this device, the user shouldn't be able to activate it again.

Proposed changes

• add a deep equality check for the peppers lists ton ensure same cards are correctly identified

Side effects

• none

Testing

1. Create a card for nuernberg or koblenz (where multiple cards can be activated)
2. Activate the card once. Then use the same qr code and try to activate the same card
3. There should be a message, that the card is already activated on your device

Resolved issues

Fixes: #1850
