Nivanka Fonseka 411f168f00 parse the string to be converted to group codes.
Two fixes.
1. parse the group code by using Convert::raw2url() as it creates duplicate records if the group code is given in upper case letters, spaces etc. 
2. assigning to the $_cache_groupByCode has to be really done in the if condition rather than out of it.
