    online-accounts: make adding an account inline to the edit dialog
    
    When adding an account, the old proccess was: use the (removed) toolbar
    to open the New Account dialog, select a provider in that dialog, add
    the account and see the newly created account in the panel itself.
    
    That approach had issues, e.g. the user would have to close the dialog
    if she mistakenly selected a provider. After moving the provider list
    to the panel itself, it doesn't make sense anymore to have another
    provider list inside the dialog.
    
    Fix this by moving the new account view to the accounts dialog.
