Equivalent to `unlock(encryptionKey)`, but does not throw in the case
that the database is already unlocked.

**RejectsWith**
[InvalidKeyException](../-invalid-key-exception.md) if the encryption key is wrong, or the db is corrupt

**RejectsWith**
[LoginsStorageException](../-logins-storage-exception.md) if there was some other error opening the database
