[FIX] account: fix the bank account onboarding

If a bank account is added through the onboarding step and the user creates one instead of linking it,
the dashboard is not reloaded to show the completion of the step and the new account.
To make sure that the view is reloaded to show new data,
the easiest fix would be to return a reload action in `validate`.
