* Attributes are stored in hash slot of glob reference.  Previously they were
  stored in hash reference pointed by scalar slot of glob reference.

  Was:

  my $obj = MooseX::GlobRef::Object->new;
  ${*$obj}->{attr} = 42;

  or:

  my $obj = MooseX::GlobRef::Object->new;
  my $hashref = ${*$obj};
  ${*$obj}->{attr} = 42;

  Should be:

  my $obj = MooseX::GlobRef::Object->new;
  *$obj->{attr} = 42;

  or:

  my $obj = MooseX::GlobRef::Object->new;
  my $hashref = \%{*$obj};
  $hashref->{attr} = 42;
