[#1253] ir: Call UpdateStateIR method to remove dead storage node

Alphabet nodes in notary enabled environment cannot call `UpdateState`
method to remove unwanted storage nodes from the network map,
because this method checks witness of the storage node.

To force storage node state update, alphabet nodes should invoke
new method `UpdateStateIR` which is similar to `AddPeerIR`.

State update initiated by the storage node itself is processed
the same way as before -- alphabet nods resign such transaction.
