ux: don't show Transaction failed error if rejected

[bonustrack]

When doing a transaction or signing a message, if the user reject the action in his wallet we shouldn't show an error message with "Transaction failed", this is a common flow where user cancel his tx. We should instead not show a modal but just show his previous step (showing proposal page or space edition etc).

Transaction failed should only appear when indeed a tx failed.
