MDL-46833 mod_assign: Fix assignment view when available for group members only.

Browse source 
When assignment is "Available for group members only" and no users with
mod/assign:submit role permision is enrolled (students),
groups_filter_users_by_course_module_visible is causing error (as $users
array is empty). The patch resolves the issue.
