Unassign Card

[jooooscha]

The first element of the three-dots-menu on an unassigned card reads “assign to me”. However, if the card is already assinged to me, this should read “unassign”. Currently, the “assign to me” button is useless, after it was used. Therefore, it could be replaced with the unassign function, which would save several clicks on unassigning a task.
