Change directory to look in for expected_2024 min bias in tests
FYI @tevans @abertoli @lugrazet
Goes with lhcb-datapkg/PRConfig!400 (merged)
As announced here, the files corresponding to expected-2024 min. bias hlt1 filtered MC are about to move, and therefore paths need updating. I changed all the ones I could find in the repo on the master branch.
Also noticed that the AllenInMoore qmtest wasn't looking at the same file as the bandwidth test proper - I got a passing qmtest but we had a failing bandwidth test overnight cc @lugrazet.
As requested, I also change the bandwidth test .yaml options to use the TestFileDB where they were not before. It should be the same files under-the-hood though, so I expect no changes to any bandwidths.
