Fix #3909. SUMPRODUCT is mishandling multi-row ranges. In Calculation/Calculation, `checkMatrixOperands` will often resize its operands. When it does so, it needs to recalculate the dimensions of each. This fixes the reported problem. Likely cause was PR #3260. That ticket noted the poor coverage of the code being replaced. Tests of the problem in this ticket were absent and are now added. Despite this, I note that `resizeMatricesShrink` is virtually uncovered, and `resizeMatricesExpand` has substantial gaps in its coverage. I have covered some, but not all, of the Expand gaps. I am struggling to come up with examples to fill its remaining gaps and those for Shrink. However, I will merge this fix in about a week even if I don't succeed.
