Calc recalculate bugs

Hi Eike,

I see that you are working on tdf#123714 and also on the related bugs
tdf#123736, tdf#120660 and tdf#120013 and you already have many fixes in.
It seems there are many sub issues mentioned by the reporter at least in
tdf#123714. I wonder if there are any sub issues there that you did/will
not get a chance to work on etc. In that case I'd be happy to help and try
fix some of the remaining ones if it is ok with you of course. Please do
let me know :)

Thanks,
Dennis
