Phase 2 of #859
Once a new batch is triggered, even if the commit head didn't change, the upgrade builds a frequently restarted because the reference builds are not the same once one of them changed.
It's not a big issue, but it can generate useless load when passing pr from draft to ready for review, or starting a new batch manually, ...
This pr proposes to have reference batches on each base branches, that will be used as reference by dev branches instead of taking the last one.
The idea to search the latest batch created before the base batch was considered, but this won't work well for freshly rebased branches since the last done may change. The easiest solution is to store all last done base batch on each base bach.
The question is, should we filter them per category?
1- before storing them?
2- store all of them and filter when needed
The actual state of the database would make 1 more logical, but looking at the current code it is possible to upgrade from the trigger from another category (use nightly databases) even if it is not really in use anymore (except for upgrade partial maybe)
