Disable the arguments append-column and delete-column of tabular-features. The code is taken from InsetMathCases, with some changes * no need to record undo here * in dispatch, return is prefered to break, since we do not want to invoke InsetMathGrid::doDispatch. Propagate these changes to InsetMathCases. Cleanup of the InsetMathCases error messages to fit with other parts of the code. The handling of tabular-features in mathed needs to be unified somehow. Based on a commit from lynx <lorenzobertini97@gmail.com> Part of bug #12590.
