Python: Minor cleanup for string pool interaction
This doesn't really seem to impact performance, is just a bit cleaner way to write the QL code.
In the worst case, since we do string concat with empty string, we would need to load string + attempt to store new string in string pool, which is useless since we can surely just reuse the integer ID.
