Enable more tests to the MCReconstructed tool
From the Rec!3283 (diffs), I realized that MCReconstructed.Chi2 and MCReconstructed.Chi2DOF were not working properly, I was surprised their tests were actually disabled in DaVinci, I fixed these bugs in Analysis!948 (merged) but it would be great if we enable their tests in DaVinci.
This MR can be merged independently.
