Get mentions metadata query example for Dutch House of Representatives doesn't work

[Ian Hopkinson]

I was trying something like this:

http://127.0.0.1:5000/dutchhouse/get_mention_metadata?uris.0=http://www.newsreader-project.eu/data/20120419/55FD-FNS1-F151-W2VK.xml%23char=1722,1730&api_key=a

In the code we have:
self.dutchhouse_example = 'get_mention_metadata?uris.0=http%3A%2F%2Fwww.newsreader-project.eu%2Fdata%2F20120419%2F55FD-FNS1-F151-W2VK.xml%23char%3D1722%2C1730'

Which looks like the code for other examples for different endpoints
