[FIX] utm: show campaign tags by default by giving them a color

Colorless tags are not displayed in kanban view of utm campaigns. When creating
tags on the fly currently they have no color and are therefore not displayed
once saving the campaign. This is not really intuitive for users.

We now set a default value to color field of tags. They are now displayed
by defauklt.
