Return reference from SignedSoftConfirmation fields

[yaziciahmet]

Description

Return reference from SignedSoftConfirmation fields, and clone them whenever the caller needs to. Also changes the txs input to apply_soft_confirmation_txs be a slice so we can avoid cloning it in couple of places. This could be useful specifically for txs since it potentially can be really big.
