refs #3736
Fixed the issue with vagrant & failing tests. The solution is to setup webserver to Piwik.
 * added documentation in the test output to prevent useless test failures messages
 * I just write out the message and exit. Not sure if that's the proper way to do this
 * also added help text in case user hasn't up

Cleanup
Need this as well to prevent error if piwik uninstalled!

 Fix bug in case REQUEST_URI does not contain the tests path

Just to be sure
PHPUnit tests for piwik require a running webserver.

travis/setup_webserver.sh will install nginx + php-fpm
and create configuration files.

travis.sh adjusted to reflect changes.

Moved everything to tests/
