Thanks very much for addressing this @ericLemanissier

I guess the packages_table.py and localdb.py suffers the same, might need same changes.

I cannot guarantee that this fix is complete and correct, but at least it fixes conan create invocations (tested at https://github.com/ericLemanissier/conan-center-index/actions/runs/8782395019/job/24096433822)

Excellent, thanks very much.

I have reviewed the code too, and it seems to be covering all occurrences.
