Different translator is used to report errors

[KES777]

https://github.com/dbsrgits/sql-translator/blob/master/t/30sqlt-new-diff-pgsql.t#L20-L27

my $tr = SQL::Translator->new;

my ($source_schema, $target_schema) = map {
  my $t = SQL::Translator->new;
  $t->parser('YAML')
      or die $tr->error;
  my $out = $t->translate(catfile($Bin, qw/data diff pgsql/, $_))
      or die $tr->error;

I suppose that the translator should be one and not two $t and $tr.
