NameKeyGenerator::nameToLowercaseKey doesn't work properly for new keys

```cpp
// Check if the lowercase key generation works correctly
NameKeyType lowerKey1 = TheNameKeyGenerator->nameToLowercaseKey("Test1234567");
NameKeyType lowerKey1Again = TheNameKeyGenerator->nameToKey("test1234567");
assert(lowerKey1 == lowerKey1Again);
```

This works for existing keys and is expected to work for new keys as well, but it doesn't.
