Refactor GetNextResourceIndex to make it work properly with transaction (#21469)

Browse Source 
Related:
* #21362

This PR uses a general and stable method to generate resource index (eg:
Issue Index, PR Index)

If the code looks good, I can add more tests

ps: please skip the diff, only have a look at the new code. It's
entirely re-written.
