Notification icons: Render empty string for "custom" setting

Merged Martin Wortschack requested to merge 254224-notification-icons-missing-icon-for-custom into master

What does this MR do?

In !40709 (merged) we update the notification icons to use our internal Gitlab SVGs.

However, when a user selects the Custom notification setting, the sprite_icon helper responds with the following error as it cannot find an icon for the custom level:

is not a known icon in @gitlab-org/gitlab-svg

This MR ensures that an empty string gets rendered in this case to prevent the "missing icon" error from showing up.


Does this MR meet the acceptance criteria?
