📔 Objective

The availableAccounts$ looks to have a default addAccount accounts, so it is not empty. The *ngIf is then truthy and the account switcher component is always shown. I've added a hasLoggedInAccount variable and added that to the check.

The changes look great, but we need to update the apps/browser/src/auth/popup/extension-anon-layout-wrapper/extension-anon-layout-wrapper.stories.ts as storybook is failing with an error: ERROR NullInjectorError: R3InjectorError(Standalone[ExtensionAnonLayoutWrapperComponent])[AccountSwitcherService -> AccountSwitcherService -> AccountSwitcherService -> AccountService -> AccountService]:
due to the addition of the new service dependency.
