Add ideLink for printed test results

[alexander-schranz]

Currently its sometimes hard when you run all tests and see that example test find by country and location is failing to get to the method call testFindByCountryAndLocation failing as you can not simple copy it from somewhere in the output.

This pull request tries to solve this issue by make use of the xdebug configuration and the console href links that the results are linked to the runned tests.

The xdebug support to configure a link format which can be used that printed stack trace is directly linked to the ide you are using:

xdebug.file_link_format = "phpstorm://open?file=%f&line=%l"

If this is now configured the output of the printer will link directly to the methods and so you can just click on them.

New output with clickable links:

Old output
