[giannis-rdx]

Description

This PR fixes a bug where the user dismiss the bottom sheet dialog when creating a new account.

How to test

This is very hard to reproduce.

Test 1

1. With an existing wallet click on "Create a New Account" at wallet screen
2. At the "Create New Account" screen type an account name and click "Continue"
3. Dismiss the biometric prompt
4. Click on the "X" button of the "Creating Account" bottomsheet dialog
5. Remain at the "Create New Account" screen and select "Create with Ledger..."
6. Add a NEW ledger device
7. Once adding ledger flow is done select the new ledger and proceed

At this point the wallet returns again back to "Create New Account" screen.

Test 2

1. Fresh install wallet
2. At "Create First Account" screen give a name and select with ledger
3. Click continue and authenticate
4. At "Choose Ledger Device" navigate back
5. And then click again "continue" at the "Create First Account" screen
6. Proceed with the flow to add a ledger
7. Once ledger is added and selected

At this point you will see (very instant) the bottomshet "Creating Account" dialog twice.

❗ In addition this crash might be related to this fix.
