GooFit still works with incorrect memory allocation (Amp4Body_TD)

[jcob95]

When using Amp4Body_TD, if setDataSize does not have the right dimensions, GooFit can still appear to function and produces a fit which is wrong but according to Minuit is convergent. For example in my branch jcob_test_branch I have added extra observables. setDataSize should therefore be set to setDataSize(numEventsToFit,9) but if I set this to setDataSize(numEventsToFit,8) things work as I have described previously. This should not happen, so I recommend adding a check to make sure the dimensions are correct or at least adding some kind of warning.

Edit: Will add a reproducible script and links to code
