[PM-23638] Fix URI checksums not being generated when cipherkey is not present (#347)

## 🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-23638

## 📔 Objective

While we only enforce decrypting correct checksums when a cipherkey is
present for that cipher, we must always upgrade to url checksums for
newly encrypted ciphers, regardless of whether the cipherkey is present
or not.

This is the case on Typescript
(https://github.com/bitwarden/clients/blob/682f1f83d9c211e886d6f05fc557eddb25c4c5c2/libs/common/src/vault/services/cipher.service.ts#L1660).
This allows us to enforce the presence of icon URLs after users went
through the key-rotation for v2 encryption based on the account security
version *instead of* being based on cipherkeys.
