Solving protoparticles problem S21

I found a problem with 2011 and 2012 MC. Probably I tested the filtering scripts in 2018 and I assumed that 2011,2012 was ok.

It seems that I made a relatively common mistake with S21 related filtering options (https://groups.cern.ch/group/lhcb-davinci/Lists/Archive/DispForm.aspx?ID=21371).

I thought that this was solved some time ago, but apparently S21r0p2 and S21r1p2 are also affected.

the solution will be to add these 2 lines to the 2011,2012 cases, create a new merge request and a new production for 2011,2012... I have tested now that adding these two lines everything works fine.
