Check the use of `make_whole` in BAT

[IAlibay]

Follow up from #3132

In #3132 we changed the BAT.py code such that make_whole is applied when dimensions is None. Before the condition was if (self._root.dimensions[:3] == 0).any().

The assumption is that this was the intended behaviour. We should double check this. @daveminh could you check this please?

[daveminh]

Sorry for the slow response. Yes I believe this was the intended behavior.
