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

if (! -d $full_dir) {

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