N3 patch fails to parse profile because no URI is given

[ylebre]

The problem is around this code, which already has a CHECKME noted:

php-solid-crud/src/Server.php

Line 444 in 4b97394

$graph->parse($data, "turtle");

This causes updates to the profile document to fail, because it is using the <> syntax in the turtle file.

The same fix should be applied to the 'insert' and 'delete' bits just below it.
