Merged from gramps40 the commits below and
verified there are no more instances of BatchTool
on trunk to change as well.

    6953: remove "undo history warning" under CLI

    Port my fix from gramps34.
    In addition, the Check tool now has a hardwired dependency
    on ProgressMeter. Make a nullifying mock locally and
    only set it to the real thing only under GUI.

    Tested with impex.sh (further stages after check still fail,
    see bug #6878).

    action 'tool' CLI handler broken w/o DISPLAY

    Preparing to port my fix for 6953: remove "undo history warning"
    when the BatchTool run from cli (e.g., "check")
    from gramps34, the ground state was worse in gramps40...
