    prefs: fix crash with -o column.foo:x

    The gui.column module is somehow special, it has no name since it is
    part of the gui module. This causes a crash when trying to invoke
    `strcmp(module->name /* NULL */, "mgcp")`.

    Always look up prefs inside gui_column_module when the given prefs
    module is "column" instead of matching two specific names.
