Evening activity does not get ready for groups with small host counts

[atbits]

If the value of "probGoShoppingAfterWork" is low or "maxGroupSize" is high relative to "nrofHosts" in a group - we end up with nodes that do not return from shopping ;-)
Following is the suggest fix - please feel free to adapt as per your coding conventions.
Note updated the logic issue in my suggested fix on 20th April. Attaching the modified file as well. This may be a short term fix - actual fix may be needed from multiple other files.
