Change directory to look in for expected_2024 min bias in tests

FYI @tevans

Goes with lhcb/Moore!3169 (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 add some extra files that are needed for the BW tests to the TestFileDB.

Can be undrafted and tested once the file move is complete.
