Admin actions panel is always hidden if show_full_result_count = False

[Никита Шультайс]

django.contrib.admin.views.main.py

        if self.model_admin.show_full_result_count:
            if self.get_filters_params() or self.params.get(SEARCH_VAR):
                full_result_count = self.root_queryset.count()
            else:
                full_result_count = result_count
        else:
            full_result_count = None

if show_full_result_count is False then full_result_count = None

self.show_full_result_count = self.model_admin.show_full_result_count
...
self.show_admin_actions = self.show_full_result_count or bool(full_result_count)

But show_full_result_count is False and bool(full_result_count) is also False
self.show_admin_actions is always hidden

Release blocker since it's a bug in a new feature in 1.8 (ModelAdmin.show_full_result_count).
