Toast for cancel sign message does not show

[mgavrila]

Issue

Cancelling a sign message does not display a toast with a specified message.

Reproduce

Issue exists on version 2.25.2 of sdk-dapp.

Root cause

Sign message URL params does not contain signSession in order for useParseSignedTransactions to be able to intercept and display the message.

Fix

Instead of adding a new param for the URL, use directly setSignTransactionsCancelMessage in order to display the errorMessage.
