[gnome-photos/wip/rishi/collection: 6/15] main-toolbar: Use switches for enums instead of if-else

    main-toolbar: Use switches for enums instead of if-else
    
    Using a switch statement lets the compiler warn us through
    -Wswitch-enum whenever we extend the enumeration range. An if-else
    block does not do that.
