Objective in this file is to exercise the part of
C<EU::MM::make_selections_defaults()> starting at:

    if (! -d $full_dir) {

Here, C<$full_dir()> would be
F</E<lt>mockhomeE<gt>/.modulemaker/ExtUtils/ModuleMaker/Personal/>.  The
approach to testing used in this version of EUMM, centered in
C<prepare_mockdirs()> auto-creates this directory.  Hence, we have to remove
part of this directory if we're to exercise this section of
C<make_selection_defaults()>.
