Fix the search result "Google Account" doesn't work.

- The "Google Account" item will launch the
  AccountDetailDashboardFragment.
  To launch the account detail page, we need the intent extras, account,
  account label and account type.
- Currently, SI doesn't support to index the intent extras, so we launch
  AccountDashboardFragment instead of AccountDetailDashboardFragment.

Fixes: 153626405
Test: manual test the search result and run Settings robotest
