[OpenSIPS-Users] Route_to_gw not pushing gw_id to the first index of avp

When accessing an avp without explicit index isn't it returning the last
# first time svp_gw_id is set
is_from_gw(, i); # avp now has (1)
# avp now has (gw1, gw2);
if we now access the avp, we can either get explicitly the specific index,
or we get the last index which is `gw2`.
So if I'm not mistaken, then I don't understand what the problem is here?
Correct me if this is wrong.
