'Rest' values in contribution tab should not be 0 when result is 0

[marc-vdm]

When calculating small databases, there is a chance that the Rest value in the contributions results table/figure is 0. When this happens, all table fields (see figure below) are 0. Would it not be better to skip the Rest line in the case the value is 0?

(If the rest value is > 0, the other columns are an empty string instead of 0 values.)
