[IMP] project, project_issue: set default kanban values as color instead of labels

Kanban state values are different from their visual display. When searching
on kanban state it is not easy to understand the link between the label
and the color. We now set the label as the color to ease matching and
searching. However in kanban view labels can be defined on the stage
itself. This way searching is done on the color while working with
tasks and issues in kanban is done using business meaning defined on
the stage.
