Fix attribute names in aliased form property test. Close gh-951.

Test expects input elements having name='id', name='name', and name='target'. Additionally, these should have id='id', id='name', and id='target' respectively. No element was provided with id='id' or name='id', but rather one element had two name attributes (illegal) with the values 'id' and 'name' respectively.
