Increase group selection gas estimate

The current group selection gas estimate doesn't include a corner case when 
group selection is triggered after previous DKG failed and some related data 
(previous tickets) must be cleaned up in the same transaction. This cause a gas 
peak which is returned after cleanup is done but the gas estimate must include 
it in order to avoid out of gas error. Increasing the value of 
groupSelectionGasEstimate to 200k should help.
