missing icons on shared boards dropdown

[grnd-alt]

Steps to reproduce

• create a Board and share it with at least one user
• click on the three dots icon (which is missing)
• observe the missing/white icon and wrong bold text in the menu (see screenshot)

Expected behavior

• all icons are visible
• Due date reminders is not bold

SideNote: without looking at the code path in detail the menu should not be that different between shared boards and unshared boards, maybe we can unify it.
