PT: wrong reference to taxonomy

[TomazErjavec]

ParlaMint-PT.xml (and ParlaMint-PT.ana) has:

ParlaMint/Samples/ParlaMint-PT/ParlaMint-PT.xml

Line 111 in 5d55e6a

<catRef scheme="#Parliament" target="#parla.uni"/>

we have now common taxonomies, so it should be
<catRef scheme="#ParlaMint-taxonomy-parla.legislature" target="#parla.uni"/>

@matyaskopp , strange that your factorise script didn't change than. Or maybe it was never run...
