Replace icon-navigation-close

There is a component used for the X-icon on closing buttons: icon-navigation-close. We built those before we introduced rcc-icon. Please replace all occurrences of buttons that use icon-navigation-close with small action buttons.

You may have to add a new icon (the X icon): If need be use the old one and remove color information.

You may also have to add a color to the buttons; use colorCatgory: 'secondary' for that 😄

Requirements

• iconNavigationClose removed from the code
• closing buttons, that used icon-navigation-close, still work and look very much like before 😄
