adapt to perl-5.18's random hash keys ordering

(translate_why_removed_one) ensure we got the right reason

(testsuite) adapt to new URPM predictible behaviour

it was previously relying on the following fixed hash order:

$ perl -MData::Dumper -e 'warn Dumper [ keys {'rr1', 'rr1', 'rr2',
'rr2'} ]; \
warn Dumper [ keys {'bb1', 'bb1', 'bb2', 'bb2-1'} ]'
$VAR1 = [
          'rr2',
          'rr1'
        ];
$VAR1 = [
          'bb1',
          'bb2'
        ];
