Don't sync bulk actions for anonymous user

There is no point in getting additional change details for bulk actions
for an anonymous user as bulk actions componenets are not shown in this
mode anyway. When user logs in list of changes will be refreshed anyway
an then details for bulk actions will be loaded.

Bug: Issue 365254275
Release-Notes: Don't sync bulk actions details for anonymous user.
