Skip slow test when Xdebug is loaded

When loaded, Xdebug slows down the data provider a lot. As the data provider is executed even when the related test is excluded with e.g. `--filter` option, this makes debugging tests with Xdebug a bit painful.

Not sure this is the best solution, I'm open to suggestions :)
