[gnome-music] view: Fix inconsistent allocations of cell renderers

    view: Fix inconsistent allocations of cell renderers
    
    GtkTreeView doesn't handle as nicely size allocation between cells in
    a column than between columns themselves. Distributing these in several
    columns makes it easier to ensure the size stays consistent across tree
    validation, which results in no jumping rows afterwards.
