Tagged list: A tasks with multiple tags can be included multiple times

[tomtom]

I have a board with a tagged list for tasks with tag #a.

I have a task with multiple tags (e.g., #a #b).

This task is included in the list for tag #a but also in the list Other tags. One could argue that it should be included only in #a since Other tags could be understood as a rest category list for tasks not yet included - just so we don't miss them.
