Integration test

[Reto Gmür <re...@apache.org>]

Hi all,

As you might be aware our integration tests have not been working correctly
for a long time,

I've remove the old project and created a test against the content launcher
in provisioning/launchers/tests/content-launcher-tests.

We obviously should have has this long before, the issues we have with the
latest release could all have been avoided by testing actual OSGi
integration.

For now they test the following:

- Upload data to the contentgraph
- Run a SPARQL ASK query against that data
- Dereference a resource described in the uploaded data

The test are run both using turte and rdf/json.

Please have a look at the tests and extend them!


Cheers,
Reto
