[SR-Users] Dispatcher: ds_is_from_list does not longer populate grp_avp

[Daniel-Constantin Mierla]

Hello,

right, the readme was mistaken. Probably grp_avp was used initially but 
changed later because it messes up when ds_is_from_list() and 
ds_select_*() are used for same requests.

I committed an update to the readme.

Cheers,
Daniel
