Assigning to an avp with index does not work as you expected - simple 
the index is ignored, being like there is no index. It can be 
implemented, though, nobody did it so far.

There is one exception for index [*] which will overwrite all avps with 
that name (when assigning $null, will delete all, otherwise will delete 
existing ones and add a new one with the value provided in the assignment).

Cheers,
Daniel
