Previously, we opened PrivacyPreferences and gave it a parameter to open
ClearBrowsingDataDialogFragment in its onCreate().

However, since the CBD dialog is now its own PreferenceFragment (as opposed to a
DialogFragment opened atop of PreferenceFragment), we can now open it directly.

This method is currently only called from the history tab. The positive effect
of this change is that opening the CBD dialog and tapping "Back" will lead you
back to the history page, not to PrivacyPreferences.

-        Bundle arguments = new Bundle();
-        arguments.putBoolean(PrivacyPreferences.SHOW_CLEAR_BROWSING_DATA_EXTRA, true);
-        intent.putExtra(Preferences.EXTRA_SHOW_FRAGMENT_ARGUMENTS, arguments);
+                ClearBrowsingDataDialogFragment.class.getName());
         activity.startActivity(intent);
     }
